Liquid crystal display device

摘要

A liquid crystal display device includes a first substrate and a second substrate. The first substrate includes a gate line and an auxiliary capacitance line extending in a first direction, a source line extending in a second direction orthogonally crossing the first direction, and a pixel electrode having a main pixel electrode arranged on the auxiliary capacitance line and extending in the first direction. The second substrate includes a common electrode having a main common electrode arranged above the gate line and extending in the first direction. A liquid crystal layer is held between the first substrate and the second substrate having liquid crystal molecules. The liquid crystal molecules are initially aligned in the first direction in a splay alignment state between the first substrate and the second substrate in a state where electric field is not formed between the pixel electrode and the common electrode.

1. A liquid crystal display device, comprising:
a first substrate including:
a pixel electrode including a main pixel electrode extending in a first direction arranged in a pixel in which the length along the first direction is shorter than that along a second direction orthogonally crossing the first direction,an electric conductive material under the main pixel electrode, anda first alignment film covering the pixel electrode; a second substrate including a second alignment film; and a liquid crystal layer held between the first substrate and the second substrate having liquid crystal molecules, wherein the pixel is formed in a rectangular shape having a pair of short ends along the first direction and a pair of long ends along the second direction, the main pixel electrode is arranged substantially in a center portion of the pixel apart from the pair of the short ends with equal distance, the first substrate includes a gate line extending in the first direction, a source line extending in the second direction, and a switching element connected with the gate line and the source line and arranged in a region that overlaps with the source line and the electric conductive material, and the switching element includes a drain line, and the drain line includes a first portion extending in the second direction and facing the source line and a second portion extending in the first direction from the first portion and facing the electric conductive material in the center portion of the pixel.
