Abstract
A display device includes a light guide plate which includes a light transmission portion and an antireflection portion at two opposite end faces and which is provided with a light extraction portion in part of a surface, respective light sources which are arranged on outer sides of the two opposite end faces, a transmission liquid crystal panel located adjacent to the light extraction portion, and a synchronous drive unit that alternately turns ON the light sources and that displays an image that is synchronous with an alternating turn-ON operation the transmission liquid crystal panel.
Claims15
A display device comprising:
- a light guide plate which includes a light transmission portion and an antireflection portion at two opposite end faces of the light guide plate and which includes a light extraction portion in part of a surface;
- respective light sources located on outer sides of the two opposite end faces;
- a transmission liquid crystal panel located adjacent to the light extraction portion;
- and
- a synchronous drive unit that alternately turns ON the pair of light sources and that displays an image that is synchronous with an alternating turn-ON operation of the transmission liquid crystal panel.
A display device comprising:
- a light guide plate including two transparent plates, each of which has a light transmission portion at one of two opposed end faces, an antireflection portion at the other of the two end faces, and a light extraction portion in part of a surface, the transparent plates being placed one over the other so that the light extraction portions are in the same direction and so that the light transmission portions are opposed to each other;
- respective light sources located on outer sides of the light transmission portions;
- a transmission liquid crystal panel located adjacent to the light extraction portions;
- and
- a synchronous drive unit that alternately turns ON the light sources and that displays an image that is synchronous with alternating turn-ON operations on the transmission liquid crystal panel.
