Abstract:
A liquid crystal display device includes: a TFT substrate having gate lines and data lines arranged thereon, the gate lines extending in a first direction and arranged in a second direction, the data lines extending in the second direction and arranged in the first direction; a counter substrate having a black matrix and a color filter; and liquid crystals put between the TFT substrate and the counter substrate. Columnar spacers are formed on the counter substrate. Pedestals are formed on portions of the TFT substrate, the portions corresponding to the columnar spacers. A convex portion and a concave portion are present at the top end of the columnar spacer. The pedestal is formed corresponding to the concave portion. The concave portion is opened at the ends thereof and connected to the lateral side of the columnar spacer.
