摘要：
A polarized light emitting device has a planar emitting device, a phase-shift device, a polarizing reflecting device, and a reflecting device. The planar emitting device emits light from a front and back surfaces of the planar emitting device. The phase-shift device transmits the light emitted from said planar emitting device, and changes the polarization direction of the light. The polarizing reflecting device transmits or reflects the light according to the polarization of the light emitted from the front surface or transmitted by said phase-shift device. The reflecting device reflects the light emitted from the back surface or transmitted by said phase-shift device.
