1. A multi-primary color display device including a plurality of pixels, each having a plurality of sub-pixels, wherein: the plurality of sub-pixels include a first sub-pixel for displaying a first color having a first hue, a second sub-pixel for displaying a second color having a second hue, a third sub-pixel for displaying a third color having a third hue, and a fourth sub-pixel for displaying a fourth color having a fourth hue; the second hue and the third hue are adjacent to the first hue on both sides thereof, among the hues corresponding to the plurality of sub-pixels on an a*b* plane of an L*a*b* colorimetric system; and when a color displayed by each pixel changes from black to an optimal color of the first hue or an optimal color of a specific hue which is closest to the first hue among the hues corresponding to the plurality of sub-pixels, luminance values of the plurality of sub-pixels are set such that the luminance value of the first sub-pixel starts to be increased and also the luminance values of the second and third sub-pixels start to be increased at a rate of increase lower than the rate of increase of the first sub-pixel.
