ABSTRACT:
An image display device and an image display system which can establish visible light communication without interfering with an image displayed at a predetermined frame rate are provided. A controller12controls a spatial light modulator in accordance with an image signal to display the image, and also modulates an intensity of a visible light output from a backlight13with a frequency higher than the frame rate of the image signal to have the visible light output from the backlight13carry additional information. A light receiver15receives the visible light and demodulates to extract the additional information. An additional information generator16outputs the additional information.
