LIQUID CRYSTAL DISPLAY DEVICE
First Claim
1. A display device comprising:
- a first substrate including a thin film transistor and a first protrusion, anda second substrate opposed to the first substrate and including an organic film and a second protrusion;
whereinthe first protrusion includes a top portion facing to a surface of the second substrate,the second protrusion includes a top portion facing to a surface of the first substrate,the top of the first protrusion is between the top portion of the second protrusion and the surface of the second substrate, andthe top of the second protrusion is separated from the surface of the first substrate.

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.
