Abstract

The present invention is intended to realize a light emitting element which is easy to fabricate, is efficient, and is able to emit light in a uniform polarization state enabling the achievement of high luminance. A light emitting element of the present invention is a light emitting element including an active layer for generating light, the light emitting element including: a first reflection layer that allows the light generated at the active layer to reflect at a reflection section in which reflection members are periodically provided, and to exit from an exiting section between the reflection members; a polarization beam splitter layer that transmits a polarized light oriented in a first direction and diffracts a polarized light oriented in a second direction orthogonal to the first direction among the light exited from the exiting section; a wave plate layer that allows the light transmitted through the polarization beam splitter layer and the light diffracted at the polarization beam splitter layer to enter, and to exit as a light of a same polarization state; and a second reflection layer that reflects the light reflected at the first reflection light.
