  • Patent number: 9013669
    Abstract: A liquid crystal display device includes a first substrate and a second substrate which are disposed to face each other with liquid crystal interposed therebetween and a sealing material which is disposed between the first substrate and the second substrate to seal the liquid crystal, wherein a side surface of the liquid crystal display device has a cut surface, and a first resin layer which is formed along the sealing material and has a height less than a gap between the first substrate and the second substrate in a display region and the sealing material are exposed at the cut surface.
    Type: Grant

  • Patent number: 8351011
    Abstract: In an liquid crystal display device which includes: an image display part having a plurality of pixels; and a sealing member which is formed between the first substrate and the second substrate while surrounding the image display part and seals the liquid crystal therein, the sealing member includes a liquid crystal filling port which is formed by cutting away a portion of the sealing member, an side-wall edge surface of the first substrate and a side-wall edge surface of the second substrate are made coplanar with a side-wall edge surface of the sealing member along the extending direction of the sealing member on at least one side of the first substrate and the second substrate where the liquid crystal filling port is formed, and the liquid crystal filling port is formed such that a width of the liquid crystal filling port is narrowed along the liquid-crystal filling direction.
