Abstract
A display device includes: a display unit including pixels arranged in a matrix therein, each of the pixels including a first sub-pixel that displays a first color component, a second sub-pixel that displays a second color component, a third sub-pixel that displays a third color component, and a fourth sub-pixel that displays a fourth color component; and a signal processing unit that receives input signals that are capable of being displayed with the first sub-pixel, the second sub-pixel, and the third sub-pixel, and calculates output signals to the first, second, third, and fourth sub-pixels. The signal processing unit generates converted input signals with changed saturation among the input signals. The signal processing unit calculates output signals to the first sub-pixel, the second sub-pixel, and the third sub-pixel based on the converted input signals and an amount of increase in brightness caused by the fourth sub-pixel.
