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.
