LIQUID CRYSTAL DISPLAY DEVICE

摘要

Disclosed is a liquid crystal display device which comprises: a light guide plate that has a light incident surface on an end face; a light source for having light incident on the light incident surface of the light guide plate; a light diffusion plate that is arranged so as to face the light guide plate; a liquid crystal layer that is arranged between the light guide plate and the light diffusion plate; and a pair of electrodes that controls the amount of light, which propagates obliquely within the liquid crystal layer and is diffused and emitted by the light diffusion plate, by producing an electric field inside the liquid crystal layer and changing the refractive index or the magnitude of the birefringence of light that has propagated within the light guide plate and obliquely entered into the liquid crystal layer from the light guide plate.
