Liquid crystal display device
View Patent ↗In one embodiment, a liquid crystal display device includes a first substrate and a second substrate arranged facing the first substrate with a gap. A plurality of pixels is arranged in a matrix of a first direction and a second direction orthogonally crossing the first direction. The length of the pixel along the first direction is shorter than that along the second direction. Each pixel includes a main pixel electrode formed on the first substrate extending in the second direction, and main common electrodes formed on the second substrate extending in the second direction and arranged so as to sandwich the main pixel electrode in the first direction. Further, each pixel includes a plurality of regions in which an inter-electrode distance between the main pixel electrode and the main common electrode in the first direction differs mutually in the respective regions.

an auxiliary capacitance line arranged between the first and second gate lines in a center of a pixel and extending in the first direction;
a pixel electrode including:
a first sub-pixel electrode extending in the first direction and facing the auxiliary capacitance line, and
a main pixel electrode including a first main pixel electrode extending in the second direction from the first sub-pixel electrode to the first gate line side in a stripe shape with a first constant width and a second main pixel electrode extending in the second direction from the first sub-pixel electrode to the second gate line side in a stripe shape with a second constant width, the second constant width being larger than the first constant width;
a second substrate arranged facing the first substrate with a gap; and
a liquid crystal layer held between the first substrate and the second substrate.
