Abstract: A display device includes a display unit in which pixels are arranged in a matrix. The pixels each include a first sub-pixel having the largest area among sub-pixels, a second sub-pixel adjacent to the first sub-pixel and having an area smaller than that of the first sub-pixel, and a third sub-pixel adjacent to the first and second sub-pixels, having an area smaller than that of the first sub-pixel, and arranged in the same column as that of second sub-pixels. First, second, and third pixels are aligned in at least one of a column direction or a row direction and each include the first, second, and third sub-pixels that can display different one of first, second, and third colors. Areas of the first, second, and third colors displayable by the first, second, and third pixels in total are equal to one another.

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.
