Liquid crystal display device
First Claim
1. A display device comprising a transistor substrate and a counter substrate opposing to the transistor substrate,wherein the counter substrate comprising a first spacer and a third spacer,the transistor substrate comprising a transistor having a drain electrode, a source electrode and a semiconductor layer, a pixel electrode electrically connecting the transistor, and a second spacer, and a fourth spacer,the first spacer opposing to the second spacer, the third spacer opposing to the fourth spacer,the first spacer has a first sidewall extending in a first direction in a plan view,the second spacer has a second sidewall extending in the first direction,the first sidewall and the second sidewall oppose to each other in the plan view,a length of the first sidewall in the first direction is longer than a length of the second sidewall in the first direction,the third spacer has a third sidewall extending in a second direction in the plan view,the second direction crosses the first direction in the plan view,the fourth spacer has a fourth sidewall extending in the second direction,the third sidewall and the fourth sidewall oppose to each other in the plan view,a length of the third sidewall in the first direction is longer than a length of the fourth sidewall in the first direction.

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.
