Abstract

A display device includes a display unit in which a plurality of pixels are arranged. One pixel includes four sub-pixels, and the display unit includes: a pixel including one each of four sub-pixels of four different colors that are a first color, a second color, a third color, and a fourth color; and a pixel including four sub-pixels, where two of the four sub-pixels are identical and are one of sub-pixels of the first color, the second color, and the third color, and remaining two of the four sub-pixels are different two of the sub-pixels of the first color, the second color, and the third color but are not one of the identical sub-pixels.

Claims (25)

1. A display device comprising a display unit in which a plurality of pixels are arranged in a matrix along a first direction and a second direction orthogonal to the first direction,

wherein the pixels include:

a first pixel including four sub-pixels of four different colors that are a first color, a second color, a third color, and a fourth color that is white; and

a second pixel including four sub-pixels, each of which has one of three colors that are the first color, the second color, and the third color,

wherein the four subpixels in the second pixel are:

two same-color sub-pixels that have a same color as one of the three colors; and

remaining two sub-pixels having colors different from each other, colors of the remaining two sub-pixels being different from the color of the two same-color sub-pixels,

wherein the sub-pixels of the pixels arranged in the matrix are arranged such that the sub-pixels of a same color, which include one of the two same-color sub-pixels of the same color, are continuously aligned:

in the second direction, the two same-color sub-pixels in the second pixels being adjacent to each other in the first direction, a sub-pixel of the fourth color in the first pixel being arranged between the two same-color sub-pixels of the second pixels that are adjacent to each other in the second direction; or

in the first direction, the two same-color sub-pixels in the second pixels being adjacent to each other in the second direction, a sub-pixel of the fourth color in the first pixel being arranged between the two same-color sub-pixels of the second pixels that are adjacent to each other in the first direction, and

wherein the first pixel and the second pixel are alternately arranged along at least one of the first direction and the second direction.

2. The display device according to claim 1 ,

wherein sub-pixels of the fourth color are arranged at a predetermined cycle along at least one of the first direction and the second direction.

3. The display device according to claim 1 ,

wherein, among the subpixels of the pixels arranged in the matrix, a first number is a number of the sub-pixels of the first color, a second number is a number of the sub-pixels of the second color, and a third number is number of the sub-pixels of the third color, and

wherein the first number, the second number, and the third number are equal.

4. The display device according to claim 1 ,

wherein, among the subpixels of the pixels arranged in the matrix, a first number is a number of the sub-pixels of the first color, a second number is a number of the sub-pixels of the second color, and a third number is a number of the sub-pixels of the third color, and

wherein the first number, the second number, and the third number are not equal.

5. The display device according to claim 1 , wherein the first color, the second color, and the third color are red, green, and blue, respectively.

6. The display device according to claim 1 , wherein the four sub-pixels included in each of the pixels are continuously arranged along one of the first direction and the second direction.

7. The display device according to claim 1 ,

wherein the sub-pixels of the pixels are arranged in the matrix such that the sub-pixels of a same color, which include one of the two same-color sub-pixels of the same color, are continuously aligned:

in the second direction, the two same-color sub-pixels in the second pixels being adjacent to each other in the first direction, and one of the sub-pixels of the fourth color being disposed between the two same-color sub-pixels of the same color in the second sub-pixels adjacent to each other in the second direction; or

in the first direction, the two same-color sub-pixels in the second pixels being adjacent to each other in the second direction, and one of the sub-pixels of the fourth color being disposed between the two same-color sub-pixels of the same color in the second sub-pixels adjacent to each other in the first direction.
