A light-emitting device used in a liquid crystal display device is provided with a planar illuminator that focuses emitted light on a predetermined light focus point, and an optical deflector that two dimensionally deflects the light from the planar illuminator. The planar illuminator switches an emission direction of the light to enable alternate switching between a first light focus state in which the predetermined light focus point is the position of a right eye of a viewer and a second light focus state in which the predetermined light focus point is the position of a left eye of the viewer. The optical deflector can modulate each of the predetermined light focus point in the first light focus state and the predetermined light focus point in the second light focus state according to movement of the viewer.
