Abstract: There is disclosed a liquid crystal display device comprising two substrates that can be taken out of large-sized substrate boards at an improved efficiency of utilization. After the two substrates are bonded together, it is not necessary to remove unwanted peripheral portions by scribing. Alignment marks are formed on the substrates to assist alignment of both substrates. Two holes are formed in a layer of a sealant material such that these holes are located in the top and bottom walls of the completed display. A liquid crystal material is injected through these holes when both substrates are bonded together.

Abstract: A circuit plate, suitable for constituting an optical modulation device, such as a liquid crystal device, includes a light-transmissive substrate, and a plurality of principal electrodes and sub-electrodes supported on the light-transmissive substrate. Each sub-electrode is disposed between an associated principal electrode and the light-transmissive substrate so as to be electrically connected with the associated principal electrode. The plurality of sub-electrodes are disposed in a region in the light-transmissive substrate with gaps therebetween which are filled with an insulating layer, the sub-electrodes and the insulating layer in combination forming a surface on which the principal electrodes are formed. Further, a plurality of projection pieces are disposed in a region on the light-transmissive substrate outside the region of the sub-electrodes so as to be free from connection with the principal electrodes and the sub-electrodes.

Abstract: A liquid crystal display apparatus has a junction panel obtained by joining a plurality of liquid crystal display panels so that display surfaces of the liquid crystal display panels become flush. The liquid crystal display panels each have picture elements for displaying images by transmitting and shielding a transmitting light, a black matrix for shielding a light which enters a position where the picture elements do not exist and a zonal sealing member for sealing liquid crystal into each picture element. A width of the sealing member on the junction surface where the liquid crystal display panels are joined is set so as to be narrower than a width of the black matrix. Joints of displayed images on a border of the liquid crystal display panels of the junction panel can be made inconspicuous, and quality of displayed images on the junction panel which is a big screen can be improved.

Abstract: A method for manufacturing a liquid crystal display device in which two transparent insulation substrates are adhered to each other and a liquid crystal is injected into an injection area defined by a seal pattern comprising sealing material. The method comprises the steps of: starting application of the sealing material to either one of the two substrates from a position different from a cutting position of the substrate to form a liquid crystal injection hole and a liquid crystal injection area, and ending the application at a position different from the cutting position to form the seal pattern; oppositely placing the two substrates, and pressing and adhering the two substrates with the sealing material; and cutting the adhered two substrates at a predetermined position and injecting the liquid crystal from the injection hole.

Abstract: The present invention features methods and apparatuses for sealing tiled, flat-panel displays (FPDs). Tile edges corresponding with the display's perimeter edges are designed with a wide seal. Interior edges, however, have narrow seals in order to maintain the desired, constant, pixel pitch across tile boundaries. In some cases, this invention applies specifically to arrays of tiles 2.times.2 or less, and, in other cases, to N.times.M arrays, where N and M are any integer numbers. The tiles are enclosed with top and bottom glass plates, which are sealed with an adhesive bond to the tiles on the outside perimeter of the tiled display. Vertical seams (where tiles meet at the perimeter of the FPD) are sealed with a small amount of polymer. The seal may be constructed between a cover plate and a back plate, sandwiching the tiles. The AMLCD edges may be coated with either a non-permeable material or a polymer having an extremely low permeability (for example, Parylene.TM.).

Abstract: A mixed material of liquid crystals and resin is dropped on at least one substrate in an amount greater than the amount needed to cover a display area for the LCD panel. The substrate is adhered to another substrate, and excess material is removed to the outside of a display area. The phase-separation of the liquid crystals and resin is carried out by irradiating light while pressure is added to at least one substrate, so that a liquid crystal display panel applied to a liquid crystal display device or a light shutter can be manufactured without applying a complex vacuum device.

Abstract: The present invention relates to a liquid crystal cell and a fabricating method thereof, more specifically, relates to a method for combining a pair of glass substrates and to a liquid crystal cell made thereby. A fabricating method according to the present invention includes steps of spreading spacers on an inner surface of a first transparent substrate provided with electrodes, and forming a seal member along the boundary edge of a second transparent substrate provided with electrodes after aligning the second substrate to be opposite to the first substrate. As the seal member is formed while the first and the second substrates are held under pressure, no special equipment is needed and no additional step of pressing is necessary after aligning the substrates. Furthermore, the seal member occupies smaller area in the alignment surfaces of the cell compared to a conventional art.

Abstract: A spatial light modulator designed to use a minimum area on the surface of a silicon substrate. This invention comprises a silicon substrate on a back plate with a glass cover that is used to seal liquid crystal between the glass cover and the silicon substrate. Most importantly, the glue seal formed to contain the liquid crystal material is between the cover glass plate and the Si substrate on only one side and the back plate on the remaining three sides. This structure allows a smaller semiconductor substrate to be used.

Abstract: A liquid crystal cell includes a color filter substrate and an opposite substrate which are overlapped on each other with a seal interposed therebetween. The seal has a liquid crystal inlet port through which liquid crystal is filled into a space enclosed by the seal between the substrates. A width of the liquid crystal inlet port is made wider than a width of an effective display area of the liquid crystal cell, so that, when the liquid crystal is filled into the liquid crystal cell, the liquid crystal flows uniformly without disturbing an orientation of the liquid crystal.

Abstract: The present invention features flat-panel displays having a mosaic of tiles, and methods of constructing and sealing them. Sealing designs are described to maintain appropriate vacuum levels for FEDs, PFPDs and LCDs. The mosaic of tiles forming a flat-panel display may include subassembly tiles, with each consisting of two, unsealed, substantially parallel plates having a structure positioned between them; these are known as s-tiles. The tiles may be enclosed by a cover plate and backplate. Non-permeable material may be deposited on the cover plate and the backplate, with solderable metal overlaid on the non-permeable material. A metallized, non-permeable spacer/connector is also located between the cover plate and backplate for hermetically sealing the perimeter of the display. A set of electrical-interconnection, metal feed-throughs can also be positioned in the non-permeable spacer/connector.

Abstract: A liquid crystal panel including a liquid crystal material between two substrates assembled together by a sealing section which is interposed therebetween and surrounds the liquid crystal material is produced by a method including the steps of laminating two base substrates which are larger than the substrates of the liquid crystal panel in a completed state, leaving a gap between the two base substrate; filling the gap between the two base substrates with a mixture of a photocurable resin and a liquid crystal material, and irradiating a prescribed area of the mixture with light to cause phase separation of the photocurable resin from the liquid crystal material and to cure the photocurable resin, thereby forming a liquid crystal region and a sealing section which surrounds the liquid crystal region and assembling the two base substrates together; and cutting the base substrates into a plurality of liquid crystal panels.
