    Abstract: A display device includes: a display panel including a display screen; a backlight having a light emission surface that illuminates the display screen of the display panel from behind; a second processor that superimposes the visible light communication signals on backlight control signals generated based on the image signal; and a second controller that divides the light emission surface of the backlight into regions and establishes a period during which control of light emission in each of the regions and control for turning off the backlight in each of the regions a different time are performed based on the backlight control signals outputted by the second processor. When superimposing the visible light communication signals on the backlight control signals, the second processor does not superimpose a visible light communication signal in a period indicating an OFF state of the backlight in the backlight control signals.
