Abstract
A display includes: a display panel; an illumination unit; and a driving unit. The illumination unit includes a pair of light transmissive substrates, two light sources, an optical modulation layer configured to exhibit diffusion or transparency for light from each of the two light sources, and an electrode. The optical modulation layer is configured to switch a wide-angle diffusion intensity and a front diffusion intensity of light emitted from the illumination unit, by switching of a magnitude of a voltage applied to the electrode. The driving unit allows a diffusion intensity ratio of the light emitted from the illumination unit in a dual-view mode to be higher than the diffusion intensity ratio in a normal mode by switching the magnitude of the voltage applied to the electrode. The diffusion intensity ratio is defined as dividing the wide-angle diffusion intensity by the front diffusion intensity.
