Liquid Crystal Seal Patents (Class 349/153)
  • Patent number: 8194224
    Abstract: Techniques are provided for unifying steps of sealing material so that the yield and the reliability of a liquid-crystal display device become high. A starting film of scanning lines is patterned so that prismatic dummy wirings 301 for the first layer which are not electrically connected are formed in regions R1 and R2, and wirings 302 extending from the pixel section are formed in a region R3, and wirings 303 having connection end portions 303a are formed in a region R4. After an interlayer insulation film is formed, the starting film of the signal lines is patterned so that the dummy wirings 304 for the second layer are formed to embed the gaps between the wirings 301 to 303, and also the wirings 305 and the wirings 303 which extend from the pixel portion are connected to each other. This permits unification of the cross-sectional structure of the sealing material formation region.

    Abstract: A substrate assembly including a first substrate, a second substrate, a sealant, and a blocking structure is provided. The first substrate has an active area. The sealant is disposed between the first substrate and the second substrate. The sealant assembles the first substrate and the second substrate and separates the first substrate and the second substrate in a cell gap to define a space, wherein the sealant has an injection opening. The blocking structure is disposed on the first substrate and located outside the active area. A distance from the blocking structure to the second substrate is smaller than the cell gap, wherein the blocking structure divides the space into a first area and a second area. The injection opening is merely located inside the first area and the active area is merely located inside the second area.

    Abstract: A liquid crystal display panel (50a) includes a pair of substrates arranged, facing each other, a liquid crystal layer provided between the pair of substrates, and a frame-like sealing member (25) configured to bond the pair of substrates with each other and enclose the liquid crystal layer. A cavity forming wall (18ba) is provided on one of the pair of substrates between the liquid crystal layer and the sealing member (25) and is configured to form a cavity region (C) therein by an upper end of the cavity forming wall contacting the other of the pair of substrates. The cavity region (C) is configured so that, when an excessive amount of a liquid crystal material which foims the liquid crystal layer is enclosed, the cavity forming wall is destroyed to cause a portion of the liquid crystal material to flow into the cavity region (C).

  • Patent number: 8102498
    Abstract: The present invention provides a liquid crystal display device realizing improved reliability by preventing occurrence of a pixel defect. A liquid crystal display includes first and second substrates. A spacer maintains a distance between the first and second glass substrates. A liquid crystal layer is provided between the first and second substrates. A pixel electrode film and a common electrode film are formed over a base insulation film of the first substrate so as to sandwich a pixel insulation film in between. The common electrode film, the pixel electrode film or both of them are partly removed in a region corresponding to the spacer, and the pixel insulation film is partly removed in that region. It prevents the film structure from being broken due to deformation of the base insulation film made of a soft material caused by a pressure applied onto the spacer.
