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.

Claims (13)

1. A display device comprising:

a display unit in which a plurality of pixels are arranged in a display region in a matrix along two directions intersecting with each other, the pixels including at least first pixels and second pixels,

wherein

each of the second pixels includes three sub-pixels corresponding to three colors including a first color, a second color, a third color,

each of the first pixels includes sub-pixels corresponding to a fourth color and two of the three colors, the fourth color being white and being different from the first color, the second color, and the third color,

each of the pixels includes three sub-pixel areas each corresponding to a respective sub-pixel,

one of the three sub-pixel areas is larger than each of the other two sub-pixel areas that have a same area,

a sub-pixel of the fourth color is in one of the other two sub-pixel areas, and

in at least one of the two directions in the display unit, the first pixel and the second pixel are alternately arranged without the first pixels being adjacent to each other.

2. The display device according to claim 1 , wherein a total area of sub-pixels of the first color, a total area of sub-pixels of the second color, and a total area of sub-pixels of the third color are equal to each other in the display region in the display unit.

3. The display device according to claim 2 , wherein the sub-pixels are arranged so that the total area of the sub-pixels of the first color, the total area of the sub-pixels of the second color, and the total area of the sub-pixels of the third color are equal to each other in units of a set of predetermined natural number of pixels arranged in the one direction,

the predetermined natural number is multiple of 6.

4. The display device according to claim 1 , wherein the first color is red, the second color is green, and the third color is blue.
