Patent ID: 8502947

Claim:
A liquid crystal display device, comprising: a first substrate including; a switching element having a semiconductor layer, a first insulating layer arranged on the switching element, a first electrode formed on the first insulating layer, a second insulating layer formed on the first electrode, a second electrode arranged on the second insulating layer facing the first electrode and electrically connected with the switching element, the second electrode having a plurality of slits in a V shape arranged along a first direction, a first alignment film covering the second electrode and processed by rubbing treatment in a first rubbing direction in parallel with a second direction orthogonally crossing the first direction, a second substrate including a second alignment film covering a surface thereof facing the first substrate and processed by the rubbing treatment in a second rubbing direction which is a reverse direction with respect to the first rubbing direction; and a liquid crystal layer held between the first substrate and the second substrate; wherein, the slit in the V shape includes; a first central portion that extends in a third direction crossing the second direction in a counterclockwise direction at an acute angle with reference to the second direction, a first end connected with one end of the first central portion and extending along a fourth direction that crosses the third direction in the counterclockwise direction at an acute angle, a second end connected with the other end of the first central portion and extending in the fourth direction, a second central portion extending in a fifth direction that crosses the second direction in a clockwise direction at an acute angle, a third end connected with one end of the second central portion and extending in a sixth direction that crosses the fifth direction in the clockwise direction at an acute angle, and a fourth end connected with the other end of the second central portion and extending in the sixth direction, and the first end and the third end are connected.
