LIGHT EMITTING ELEMENT AND IMAGE DISPLAY APPARATUS USING THE LIGHT EMITTING ELEMENT
First Claim
1. A light emitting element including an active layer for generating light, the light emitting element comprising:
- a polarizer layer including a first region that transmits polarized light in a first direction and reflects other light from among the light generated at the active layer, and a second region that transmits polarized light in a second direction orthogonal to the first direction and reflects other light from among light generated at the active layer;
a wave plate layer including a third region and a fourth region that allows the lights exited from the first region and the second region to enter, and to exit as light in a same polarization state; and
a reflection layer that reflects the lights reflected at the first region and the second region.

Abstract
A light emitting element which can emit light in a uniform polarization state at a high efficiency and a higher luminance level is realized. The 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 polarizer layer including a first region that transmits polarized light in a first direction and reflects other light from among the light generated at the active layer, and a second region that transmits polarized light in a second direction orthogonal to the first direction and reflects other light; a wave plate layer including a third region and a fourth region that allow the lights exited from the first region and the second region to enter, and to exit as light in the same polarization state; and a reflection layer that reflects the lights reflected at the first region and the second region.
