Abstract: According to an aspect, a display device includes an image display panel and a signal processing unit. The signal processing unit derives a generation signal for a fourth sub-pixel in each of pixels based on an input signal for a first sub-pixel, an input signal for a second sub-pixel, an input signal for a third sub-pixel, and an extension coefficient. The signal processing unit derives a correction value based on a hue of an input color corresponding to a color to be displayed based on the input signal for the first sub-pixel, the input signal for the second sub-pixel, and the input signal for the third sub-pixel. The signal processing unit derives the output signal for the fourth sub-pixel in each of the pixels based on the generation signal for the fourth sub-pixel and the correction value and outputs the output signal to the fourth sub-pixel.
