Abstract:
1. A liquid crystal display device comprising: a TFT substrate having an organic passivation film; a counter substrate, the counter substrate being adhered to the TFT substrate by a sealant formed at a periphery thereof; liquid crystals put inside of the liquid crystal display device; a columnar spacer formed on the counter substrate, the columnar spacer defining a distance between the TFT substrate and the counter substrate; and a concavo-convex pedestal formed in a pixel region of the TFT substrate, the concavo-convex pedestal being provided in facing relation to the columnar spacer; wherein the concavo-convex pedestal is formed with a convex portion and a concave portion at a bottom of the concavo-convex pedestal, and a height of a top end of the convex portion is lower than that of a planar portion of an upper surface of the organic passivation film, wherein a thickness of an alignment film present on the convex portion is smaller than a thickness of an alignment film present on the concave portion, wherein a top end of the columnar spacer is in contact with two or more convex portions formed on the bottom of the concavo-convex pedestal, and wherein an area at the bottom of the concavo-convex pedestal is larger than an area at the top end of the columnar spacer.
