  • Patent number: 9360709
    Abstract: A TFT substrate and a counter substrate are bonded via a seal material. Alignment films are applied to entire surfaces of the TFT substrate and the counter substrate so as to realize even thickness of the alignment film. This allows a display region to be formed up to the area around the seal material. The alignment film is photo-alignment processed. An organic film formed of the material which is not photo-aligned is interposed between the alignment film and the seal material. High bonding strength between the organic film and the seal material improves reliability of a seal portion as well as reduces a frame region.
