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.
