DISPLAY DEVICE

摘要

A display device has a liquid crystal panel that switches between a transparent state and an opaque state, a first light source, a light guide plate arranged on a back surface of the liquid crystal panel and made of a transparent material, the light guide plate having an incident surface facing the first light source and an outgoing surface facing the back surface of the liquid crystal panel, propagating light emitted from the first light source and incident through the incident surface, and outputting the light toward the liquid crystal panel from the outgoing surface, and a second light source configured to illuminate an object arranged on an opposite side to the liquid crystal panel with the light guide plate interposed therebetween.

主权项

1. A display device comprising:
a liquid crystal panel that switches between a transparent state and an opaque state; a first light source; a light guide plate arranged on a back surface of the liquid crystal panel and made of a transparent material, the light guide plate comprising an incident surface facing the first light source and an outgoing surface facing the back surface of the liquid crystal panel, propagating light emitted from the first light source and incident through the incident surface, and outputting the light toward the liquid crystal panel from the outgoing surface; a second light source configured to illuminate an object arranged on an opposite side to the liquid crystal panel with the light guide plate interposed therebetween; and a controller configured to put the liquid crystal panel into the opaque state when the first light source is lit, to put the liquid crystal panel into the transparent state when the second light source is turned off while the second light source is lit, and to turn off the first light source.
