Abstract
According to an aspect, a display device includes: an image display unit provided with a plurality of pixels each including a first sub-pixel for displaying a first color component, a second sub-pixel for displaying a second color component, a third sub-pixel for displaying a third color component, and a fourth sub-pixel that has higher luminance or higher power efficiency for display than that of the first sub-pixel, the second sub-pixel, and the third sub-pixel, and displays an additional color component different from the first sub-pixel, the second sub-pixel, and the third sub-pixel; a replacement ratio calculation unit that calculates a replacement ratio, generates an output signal based on the replacement ratio, and outputs the generated output signal to a drive circuit.
