Liquid crystal display device

摘要

An array substrate includes a pixel electrode having a contact portion, a pair of main pixel electrodes extending in a first direction from the contact portion, and a sub-pixel electrode arranged between the contact portion and an end of the main pixel electrode so as to connect the main pixel electrodes. A counter substrate includes a common electrode having first, second and third main common electrodes. The third main common electrode is arranged substantially in the center between the pair of main pixel electrodes. A sub-common electrode is arranged between the contact portion and the sub-pixel electrode in the first direction. The third main common electrode includes a cutout portion, and the sub-pixel electrode crosses the third main common electrode at the cutout portion. The first sub-common electrode includes cutout portions, and the pair of main pixel electrodes cross the first sub-common electrode at the cutout portions, respectively.
