Abstract: A display device of the present disclosure is a display device capable of outputting, by a Carousel method, a visible light communication signal including a plurality of signal units. The display device includes a display panel that displays a video signal, a visible light communication processor that encodes the signal units, divides the encoded signal units into a plurality of blocks, generates a plurality of transmission frames by using the plurality of blocks, and uses the generated transmission frames as a backlight control signal, and a backlight that illuminates the display panel from the back surface of the display panel based on the backlight control signal. With regard to the plurality of transmission frames corresponding to one of the signal units generated by the visible light communication processor, an order of the plurality of blocks is different between at least two of the transmission frames.
