ILLUMINATION UNIT, DISPLAY, AND ELECTRONIC APPARATUS

摘要

Provided is an illumination unit capable of utilizing back light. Also provided are a display and an electronic apparatus each including this illumination unit. A display includes a display panel, and an illumination unit configured to illuminate the display panel. The illumination unit includes a light-guiding plate, a diffusion modulation device, and a reflection modulation device in this order, from the display panel side. The light-guiding plate has a light source on a side face thereof. The diffusion modulation device is capable of performing modulation between a first state of diffusing light from the light source, and a second state of allowing incident light from a back face side to pass to a front face side. The reflection modulation device is capable of performing modulation between a third state of reflecting transmitted diffused light of the diffusion modulation device to a front face side, and a fourth state of allowing incident light from a back face side to the front face side.
