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.

Abstract: A liquid crystal display device filled with a liquid crystal according to one drop filling prevents the liquid crystal from penetrating between a sealant and a TFT substrate or a counter substrate so as to reduce bonding strength in a seal part. The seal part has a wall spacer around the periphery of the sealant. In a terminal-side seal part, a second sealant is formed outside the wall spacer while a second wall spacer is formed outside the second sealant. Thus, the sealant, the wall spacer, and the sealant are sequentially formed in a plan view of a motherboard including liquid crystal display panels to be separated. This configuration can prevent the liquid crystal from penetrating into the seal part according to an internal pressure.
