Subpixels in the pixels include a first subpixel including an electrode having an opening with a longitudinal direction along a first direction and a second subpixel including an electrode having an opening with a longitudinal direction along a second direction. The first and second directions are different from the row and column directions. Subpixels arranged in a third direction are the first or second subpixels. The number of subpixels constituting one color pattern in a fourth direction is 2α. The number of subpixels in which the first and second subpixels arranged in the fourth direction constitute one cycle is 4α. The third direction is one of the row and column directions, and the fourth direction is the other direction.
