Abstract: A cassette facilitates the inspection of liquid crystal panels and prevents breakage of the liquid crystal panels. The cassette includes a frame, plates arranged substantially parallel at top and bottom portions of the frame, and slots secured to the plates so as to secure the liquid crystal panels arranged within the cassette.
Abstract: A color filter is provided with red, green and blue color filter segments. When chromaticity coordinates (x, y) in a chromaticity diagram of XYZ color specification system are measured with the color filter being sandwiched between two polarizers, a chromaticity (xp, yp) of parallel-transmitted light and a chromaticity (xc, yc) of orthogonal-transmitted light satisfy the following formula (1): ?xy=[(xp?xc)2+(yp?yc)2]1/2<0.130??(1) A liquid crystal display device is provided with such a color filter.
Abstract: An object of the present invention is to provide a liquid crystal display having a high luminance and a high contrast and a fabrication method thereof. To achieve the above object, a liquid crystal display of the present invention includes a liquid crystal panel for displaying an image by changing transmittance of a display light and one or more structures (151), (152) for dividing a pixel (103) of the liquid crystal panel into a plurality of domains (391), in which at least part of the structure (151) is constituted by a light-transmitting portion (151B) and a light-non-transmitting portion (151A).

Abstract: A method of manufacturing an image display medium for encapsulating powdered display elements uniformly between opposed substrates, and an image display medium. Spacer particles are formed in a grid pattern on a first flat substrate pulled out from a first film roll by a first electrostatic application apparatus, and spacers are formed on the first flat substrate by fixing by a first fixer. Then, black particles are applied on the entire surface by a second electrostatic application apparatus, and then white particles are applied on the entire surface by a third electrostatic application apparatus. Subsequently, black particles and white particles are removed from each upper surface of the spacers by a blade, and a second flat substrate pulled out from a second film roll is superimposed thereon, and each upper surface of the spacers is fixed to the second flat substrate by a second fixer.
Abstract: A rear-projection display for providing uniform brightness to images projected onto a screen. An auxiliary mirror, which allows a portion of incident light to pass therethrough and reflects another portion of the light, is disposed between a light source and an image display such that only a portion of the light from said light source is incident upon said auxiliary mirror. A main reflection mirror reflects light emitted from the light source and directs the light through an image display. The reflected light from the auxiliary mirror is incident on the main mirror.
Abstract: In a color liquid crystal projection display in which three differently-colored illuminating beams (R,G,B) are incident from mutually different directions on an LC panel (20) having an array of display elements (40) with a microlens array (21) at the input side of the panel comprising microlens elements (42) overlying groups of display elements that direct light from the beams through respective sets of display elements, and a projection lens (30) projects the output beams from the panel onto a screen (31), the beam geometries are selected such that at a position spaced from the output side of the panel the three output beams pass respectively through substantially separate areas and filter means (50) are disposed at that position to remove unwanted color stray light at each area thus improving color purity.
Abstract: When two substrates for a polymer-dispersed liquid crystal display panel are joined with a polymer-dispersed liquid crystal layer therebetween, a substrate supporting stage of a substrate joining machine is controlled to keep the uniformity in the screen of a space between the two substrates at a visually satisfactorily uniform level, thereby enabling to produce a liquid crystal display device provided with a polymer-dispersed liquid crystal layer having high uniformity in the screen. The above stage is preferably a transparent plate such as a quartz substrate. The transparent plate is used to uniformly and effectively irradiate the liquid crystal layer with ultraviolet rays to cure the liquid crystal layer by photo-setting.
