Abstract
Disclosed is an MVA type liquid crystal display device (LCD 100A) forming four domains in which liquid crystal molecules fall in different directions that are about 90° apart. The MVA type liquid crystal display device includes a plurality of pixels arranged in a matrix of rows and columns, which pixels are horizontally long pixels having longer sides extending in the row direction. Each pixel includes two first electrodes (21a and 21b) arranged side by side along the row direction. Preferably, at least one of the two first electrodes (21a and 21b) has a first corner section including a first edge that is parallel to the row direction and a second edge that is parallel to the column direction, and the first substrate further includes an electrode layer (16c) overlapping at least a portion of the first edge or the second edge of the first corner section. According to the present invention, display quality deterioration caused by disturbed alignment of liquid crystal molecules occurring near the edges of the pixel electrodes can be suppressed.
