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 one embodiment, a display apparatus includes a display device and an image display control circuit. The display device includes a display panel and a light controller. The light controller controls a direction of a light ray emitted from the display panel. The image display control circuit controls the display panel to display an image in which two or more parallax images having different parallax numbers are mixed, on a display surface of the display device. The image display control circuit displays a parallax image having a first parallax number in at least a first area and displays a parallax image having a second parallax number in a second area. The second parallax number is smaller than the first parallax number.
