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.

摘要： A display device improves brightness while minimizing an increase in the number of source drivers. When a value obtained by dividing the length of a display screen in a row direction by the number of pixels in the row direction is a length corresponding to one pixel in the row direction, one period of color arrangement in the row direction is a length corresponding to two pixels. One such period of color arrangement include two groups of subpixels that include first subpixel of the light's three primary colors of red (R), green (G) and blue (B), that are arranged in a row and that have the same subpixel configuration; and at least one additional subpixel. Scanning lines extending in the row direction and signal lines extending in the column direction are connected to the first subpixels and the at least one additional subpixel.
