Liquid crystal display device

A liquid crystal display device, comprising:

• a first substrate including:
• first and second gate lines extending in a second 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, and the first alignment treatment direction being set from the first gate line toward the second gate line;
• a second substrate including:
• 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 first sub-pixel electrode connected with the other end side of the main pixel electrode located closer to the second gate line and a second sub-pixel electrode connected with the one end side of the main pixel electrode located closer to the first gate line.
