Patent ID: 8885127

Claim:
A liquid crystal display device, comprising: a first substrate; a second substrate provided opposite to the first substrate; a liquid crystal layer interposed between the first and second substrates; and a sealing material interposed between the first and second substrates and surrounding the liquid crystal layer to enclose the liquid crystal layer, wherein each of the first and second substrates includes a pixel region serving as a display region and a picture-frame region serving as a non-display region surrounding an outer periphery of the pixel region and including a region where the sealing material is formed, on each of a surface of the first substrate facing the liquid crystal layer and a surface of the second substrate facing the liquid crystal layer, an alignment film formed by curing an alignment film material having fluidity spreads from the pixel region toward the picture-frame region, the first substrate includes a support substrate, a wiring layer formed on the support substrate, and an insulating film covering the wiring layer on the support substrate and having a surface located opposite to the support substrate and partially and directly covered with the alignment film, a recess portion which does not penetrate the insulating film is formed on a surface of the insulating film, as seen perpendicularly to a surface of the support substrate, the recess portion at least partially overlaps the wiring layer, a bank of the recess portion is located in the picture-frame region and has such a shape that a tangent plane of the bank increases in inclination toward the support substrate as the tangent plane is shifted toward a bottom of the recess portion, and an edge end of the alignment film is supported by the bank of the recess portion whereas the bottom of the recess portion supporting the edge end of the alignment film is uncovered by the alignment film.
