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.

Abstract: Each pair of pixels including two pixels adjacent to each other includes two first sub pixels, two second sub pixels, and two third sub pixels. One of the two first sub pixels and one of the two second sub pixels are included in one of the pair of pixels. The other of the two second sub pixels and one of the two third sub pixels are included in the other of the pair of pixels. The other of the two third sub pixels and the other of the two first sub pixels are disposed across and included in both of the pair of pixels. The drive circuit allocates the gradation data of one pixel to the gradation data of another pixel adjacent to the one pixel and drives the first, second, and third sub pixels included in the other pixel based on the gradation data of the other pixel.
