Abstract

According to an aspect, a display device includes an image display panel in which pixels each including first to fourth sub-pixels are arranged in a two-dimensional matrix; and a signal processing unit that converts an input signal into an output signal and outputs the generated output signal to the image display panel. The signal processing unit determines an expansion coefficient, obtains a generated signal of the fourth sub-pixel in each pixel based on input signals of the first to the third sub-pixels in the pixel itself and the expansion coefficient, obtains an output signal for the fourth sub-pixel in each pixel based on a generated signal of the fourth sub-pixel in the pixel itself and a generated signal of the fourth sub-pixel in an adjacent pixel to be output to the fourth sub-pixel.
