  • Patent number: 7889307
    Abstract: A space between substrates in a liquid crystal optical modulator can be sealed with a metal by using a simple configuration. In a seal structure between the substrates constituting a liquid crystal cell in a liquid crystal optical modulator, metal members are provided on the opposing surfaces of the two substrates, and the base metal surfaces of the metal members are brought into direct contract and joined. As a result, a low-melting metal such as a solder that has been conventionally introduced into the joint section becomes unnecessary, and a metal seal providing for strong bonding can be formed with a simple configuration. The liquid crystal optical modulator has a first substrate having a first electrode pattern including a pixel electrode, a second substrate having a second electrode pattern including a counter electrode, and a metal seal disposed so as to be sandwiched between the first substrate and the second substrate.

  • Patent number: 7889306
    Abstract: A liquid crystal display and a method of fabricating the same is capable of strengthening adhesion between a sealant and a lower plate in a panel with a high aperture ratio to which an organic protective film is applied. The organic protective film and a gate insulating film are patterned in such a manner that the sealant comes into contact with a substrate directly. Accordingly, the organic protective film or the gate insulating film at the area coated with the sealant is partially or entirely removed to directly contact the sealant with the gate insulating film or the lower glass, thereby strengthening the adhesion between the sealant and the lower plate.

  • Patent number: 7868991
    Abstract: In a wiring figure pattern of a display panel, each wiring is separated into bands of optimal widths by slits of a constant width as a wiring figure pattern so that minimum light irradiation for curing a photocuring sealing material can be carried out without increasing the electric resistance of the wiring. The optimal width means a resistance such that light coming from both sides of the band cures the sealing material on the upper surface of the band without influencing the driving and display of liquid crystal. At a point where the width of wiring becomes two times or more of the optical width between the start point and end point of intersection of the wiring and the sealing material region, the wiring is divided by the slit. A first branch forms the band of the optimal width extending from the branch point to the end point, whereas the second branch extends to the end point and is spaced apart from the first branch by the width of the slit.

  • Patent number: 7817236
    Abstract: A display substrate includes a transparent plate and a liquid crystal dispersion adjuster. The display substrate includes a display area and a peripheral area surrounding the display area. The liquid crystal dispersion adjuster is formed in the peripheral area to modify the movement of the liquid crystal. The dispersion adjuster includes enhancing parts and a suppression part. The enhancing parts increase the dispersion of the liquid crystal, and the suppression part reduces the dispersion of the liquid crystal, thereby reducing non-filling area of the liquid crystal and the contamination of a seal-line.
