Abstract: According to an aspect, a display device includes: a display unit including a plurality of pixels; and an image processor configured to generate an image signal for displaying an image on the display unit. When the image processor causes the display unit to display the image such that a first pixel region that displays a first color is adjacent to a second pixel region that displays a second color and that has luminance higher than luminance of the first color, the image processor applies gain to an image signal corresponding to a pixel in the second pixel region to make brightness of the second pixel region lower than brightness of the first pixel region.
