Abstract:
1. A liquid crystal display device comprising: drain lines extended in a first direction and arranged in parallel in a second direction; gate lines extended in the second direction and arranged in parallel in the first direction; a common electrode, formed to be planar, into which a common signal which is a reference is input; a linear pixel electrode disposed on a liquid crystal layer side across an insulating film and disposed superimposed over the common electrode; and a thin film transistor which supplies a video signal from the drain lines to the pixel electrode in synchronism with a scan signal from the gate lines, wherein the drain lines are such that one drain line is formed for every two pixels adjacent to each other within the same pixel row, the gate lines are formed of a first gate line connected to one of the two pixels connected to the same drain line within the same pixel row and a second gate line connected to the other pixel, the pixel electrode is formed of a first linear electrode inclined in a plus direction to form a first acute angle to the first direction, and a second linear electrode inclined in a minus direction to form a second acute angle to the first direction, in a region in which the pixel electrode is superimposed over the common electrode, and each pixel includes the first and second gate lines and the thin film transistor formed in a region at a center of the pixel along the first direction between the region of the first linear electrode and the region of the second linear electrode, a first extension portion is extended from the drain line in the second direction and formed between adjacent pixels, a second extension portion different from the first extension portion is extended from the drain line in the second direction and formed between adjacent pixels, and the first extension portion and the second extension portion are disposed opposed to each other in the second direction with a gap.
