Abstract: In order to avoid generation of black unevenness caused by the water intrusion into a liquid crystal display device, there is to provide a liquid crystal display device including a display area and a terminal portion, in which a TFT substrate with an organic passivation film formed and an opposite substrate are adhered to each other by a seal portion and a liquid crystal is enclosed there, wherein in the seal portion of the TFT substrate, a groove-shaped through-hole is formed in the organic passivation film to surround the display area, a water absorption layer formed of the same material in the same process as that of the organic passivation film is formed within the groove-shaped through-hole, and the water absorption layer is not covered with the inorganic insulating film.

Abstract: There is achieved a liquid crystal display device having a smaller picture frame region and a seal part of improved reliability. A liquid crystal display device includes a TFT substrate having a display region and a terminal region and formed with an organic passivation film, a counter substrate attached to the TFT substrate through a seal part, and a liquid crystal contained inside the seal part. A hole is formed at a predetermined pitch on the organic passivation film of the TFT substrate corresponding to the seal part when viewed on a plane. When the hole is viewed on a plane, a shortest distance from the hole to the hole is four micrometers or greater and 12 micrometers or less at a height of h1=0.9×h2 from a bottom face of the hole, where a depth of the hole is defined as h2.
