Abstract
A display device includes a pixel defined by a plurality of sub-pixels. The plurality of sub-pixels include first, second, third and fourth sub-pixels. A second hue of the second sub-pixel is closest to a first hue of the first sub-pixel in the chromaticity diagram of the L*a*b* color system, and a third hue of the third sub-pixel is closest to the first hue on the opposite side to the second hue with respect to the first hue in the chromaticity diagram of the L*a*b* color system among the hues. The luminances of the plurality of sub-pixels are set such that while a color displayed by the pixel changes from black via the first color of the first sub-pixel to white, the luminance of the first sub-pixel starts to be increased, and when the luminance of the first sub-pixel reaches a predetermined luminance, the luminance of at least one of the second sub-pixel and the third sub-pixel starts to be increased.

30. A display device comprising a pixel, wherein:
-
the pixel can perform display with any combination of a first color having a first hue, a second color having a second hue, a third color having a third hue and a fourth color having a fourth hue at any luminance; the second hue is closest to the first hue in a chromaticity diagram of the L*a*b* color system among the hues of the pixel, and the third hue is closest to the first hue on the opposite side to the second hue with respect to the first hue in the chromaticity diagram of the L*a*b* color system among the hues of the pixel; and the luminances of the colors of the pixel are set such that while a color displayed by the pixel changes from black via the first color to white, the luminance of the first color starts to be increased, and when the luminance of the first color reaches a predetermined luminance, the luminance of at least one of the second color and the third color starts to be increased.
