摘要:
A liquid crystal display device includes a TFT substrate having an organic passivation film, and a counter substrate, with liquid crystals inside of the liquid crystal display device. A columnar spacer is formed on the counter substrate, which defines a distance between the TFT substrate and the counter substrate, and a concavo-convex pedestal is formed in a pixel region of the TFT substrate, the concavo-convex pedestal being provided in facing relation to the columnar spacer. The concavo-convex pedestal is formed with a convex portion and a concave portion at a bottom of the concavo-convex pedestal, with a top end of the columnar spacer being in contact with two or more convex portions formed on the bottom of the concavo-convex pedestal, and an area at the bottom of the concavo-convex pedestal being larger than the area at the top end of the columnar spacer.
