Abstract: According to an aspect, a display device includes a plurality of pixels. Each pixel includes two sub-pixels adjacent to each other in a first direction. Each sub-pixel has one of three colors allocated thereto. Two colors of the two sub-pixels included in the pixel are different. The two colors of the two sub-pixels and a positional relation between the two sub-pixels are the same in each of the pixels arrayed in a second direction. One color not allocated to the two sub-pixels included in a first pixel out of the three colors is allocated to at least one of the sub-pixels included in second pixels adjacent to the first pixel in the first direction. The sub-pixels having the same color allocated thereto are arranged along the first direction with one sub-pixel interposed therebetween, the one sub-pixel having another color allocated thereto.

Abstract: According to an aspect, a display device includes an image display panel including: sub-pixel rows, in each of which sub-pixels for displaying different colors are periodically arrayed in a first direction, are regularly arranged in a second direction different from the first direction; signal lines in parallel to sub-pixel columns in which the sub-pixels are successively arranged in the second direction; and scan lines that sequentially select each sub-pixel row. Each of m (integer≥2) selector signals selects n (integer 1) pairs of the signal lines each supplied with two signals each having a mutually reverse polarity, within a period during which each sub-pixel row is selected by a corresponding scan line, and a sum of potential changes of the n pairs of the signal lines selected by each selector signal is substantially zero when each sub-pixel row is sequentially selected by the corresponding scan line.

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.
