Abstract: According to an aspect, a display device includes a display unit in which a plurality of pixels are arranged in a matrix along two directions intersecting with each other. Each of the pixels includes three sub-pixels corresponding to three of four colors including a first color, a second color, a third color, and a fourth color. An area of one sub-pixel among the three sub-pixels is larger than the area of each of the other two sub-pixels. A sub-pixel of the fourth color is one of the other two sub-pixels. Pixels each including the sub-pixel of the fourth color are not adjacent to each other in at least one of the two directions in the display unit.

Abstract: A display device includes a display unit in which pixels are arranged in a matrix. The pixels each include a first sub-pixel having the largest area among sub-pixels, a second sub-pixel adjacent to the first sub-pixel and having an area smaller than that of the first sub-pixel, and a third sub-pixel adjacent to the first and second sub-pixels, having an area smaller than that of the first sub-pixel, and arranged in the same column as that of second sub-pixels. First, second, and third pixels are aligned in at least one of a column direction or a row direction and each include the first, second, and third sub-pixels that can display different one of first, second, and third colors. Areas of the first, second, and third colors displayable by the first, second, and third pixels in total are equal to one another.

Abstract: A display device includes a display unit having a display surface on which pixels are arranged in row and column directions. Each pixel includes subpixels having different colors. 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.
