Abstract

A liquid crystal display device includes a display area in which pixels are disposed in a matrix with rows and columns. The display area includes first and second configuration columns. The first configuration column is a column where first pixels are aligned. The first pixels each include a pixel electrode including first and second areas. In the first area, electrodes extending in a first direction inclined to the column direction are disposed. In the second area, electrodes extending in a second direction inclined differently from the first direction are disposed. The second configuration column is a column where second and third pixels are alternately aligned. The second pixels each include a pixel electrode including electrodes extending in a third direction inclined to the column direction. The third pixels each include a pixel electrode including electrodes extending in a fourth direction inclined differently from the third direction.
