Abstract

Provided are an illumination device which allows for the use of a backlight a display device equipped with the illumination device and an electronic device. The display device is provided with a display panel and the illumination device for illuminating said display device. The illumination device comprises sequentially from said display panel side a light guide plate having a light source on the side face thereof a spread spectrum modulation element which can modulate between a first state where the light from said light source is spread and a second state where the incident light from the rear side is transmitted through the front side and a reflection modulation element which can modulate between a third state where the spread and transmitted light of said spread spectrum modulation element is reflected in the front direction and a fourth state where the incident light from the rear side is transmitted through the front side.
