Abstract
According to an aspect, a display device includes a display panel including sub-pixels of three primary colors, and pixels having a high-luminance color having higher luminance than that of the primary colors. The three primary colors include a first primary color, a second primary color, and a third primary color. The number of the sub-pixels is smaller than twice the number of the pixels, sub-pixels of the same color are arranged at even intervals in a row direction and at even intervals in a column direction, and the sub-pixels of the same color are arranged in a staggered manner.

- the pixels are arranged in a matrix along the row and column directions.
The display device according to 1, wherein one of the sub-pixels having the first primary color, one of the sub-pixels having the second primary color, and one of the sub-pixels having the third primary color are adjacent to each of the pixels.
The display device according to 2, wherein
- the pixels are trapezoidal, and two parallel sides of each of the pixels along a predetermined direction have respective lengths at a ratio of 1 to 2, and
- two sides of each of the sub-pixels along the predetermined direction have a length that is the same as a length of a shorter one of the two parallel sides of the pixel.
The display device according to 2, wherein
- the pixels and the sub-pixels are rectangular, and
- parallel sides of each of the pixels that extend along a predetermined direction and that are adjacent to the sub-pixels have a length that is 1.5 times a length of a side along the predetermined direction of each of the sub-pixels.
The display device according to 2, wherein
- the pixels and the sub-pixels are arranged along a first direction in pixel rows and sub-pixel rows, respectively, and pixel rows and sub-pixel rows are alternately arranged along a second direction orthogonal to the first direction, and
