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.
