Patent ID: 8873009

Claim:
A liquid crystal display device, comprising: a first substrate including: first and second gate lines extending in a first direction, first and second source lines extending in a second direction orthogonally crossing the first direction, a pixel electrode having a main pixel electrode in the shape of a belt, and a first alignment film covering the pixel electrode, the first alignment film being alignment processed in a first alignment treatment direction substantially in parallel with an extending direction of the main pixel electrode; a second substrate including: a common electrode having a main common electrode arranged on both sides sandwiching the pixel electrode and extending substantially in parallel with the extending direction of the main pixel electrode, and a sub-common electrode extending in the first direction crossing the extending direction of the main pixel electrode on one end side of the main pixel electrode located closer to the second gate line, wherein the first alignment treatment direction is set from the second gate line toward the first gate line, and a second alignment film alignment processed in a second alignment treatment direction substantially in the same direction as the first alignment treatment direction; a liquid crystal layer held between the first substrate and the second substrate and having liquid crystal molecules, wherein the pixel electrode includes a sub-pixel electrode connected with the other end of the main pixel electrode located closer to the first gate line and formed in the shape of a diamond.
