Abstract
A light emitting diode includes a semiconductor layer sequence stack, a reflective polarizing layer and a diffuse reflection structure. The semiconductor layer sequence stack includes first and second semiconductor layers, and a light emitting layer disposed therebetween. The reflective polarizing layer is disposed on the semiconductor layer sequence stack. The diffuse reflection structure is disposed on the light emitting layer opposite to the reflective polarizing layer. A light emitting device including the light emitting diode, and a projector including the light emitting device are also provided.
