Abstract
A light-emitting device including a light source that exhibits polarization anisotropy and a reflector that is shaped so that for light emitted in at least two directions from the light source, the angle between the dominant polarization directions after reflecting from the reflector is smaller than the angle between the dominant polarization directions before reflecting from the reflector. In the light-emitting device the light source may be a light-emitting diode chip or one of a plurality of light sources.
