Patent ID: 8891052

Claim:
A liquid crystal display device, comprising: a light emitting unit configured to emit light; an optical deflector that deflects the light emitted by the light emitting unit; a control unit configured to control a light deflection angle of the optical deflector; and a liquid crystal panel that forms an image from the light traveling from the optical deflector, wherein the optical deflector includes a first optical deflector and a second optical deflector which are arranged side by side in a direction from a light incident side to a light emitting side, a maximum light deflection angle of the first optical deflector is smaller than a maximum light deflection angle of the second optical deflector, and a maximum light deflection speed of the first optical deflector is higher than a maximum light deflection speed of the second optical deflector, each of the first optical deflector and the second optical deflector includes a plurality of liquid crystal deflection elements arranged in a planar state, the control unit is configured to apply a voltage to each of the liquid crystal deflection elements to control a refractive index of the each of the liquid crystal deflection elements, thereby controlling a light deflection angle of the first optical deflector and a light deflection angle of the second optical deflector, and the first optical deflector includes a plurality of optical deflection layers stacked in the direction from the light incident side to the light emitting side, each of the optical deflection layers including the liquid crystal deflection elements arranged in the planar state.
