Abstract
The light emitting element includes and active layer that produces light; a polarizer layer having a first region that allows a polarization component in a first direction in the light produced in the active layer to pass through and reflects other polarization components, and a second region that allows a polarization component in a second direction perpendicular to the first direction to pass through and reflects other polarization components; a wave plate layer having a third region and a fifth region that the light exiting from the first region enters, and a fourth region and a sixth region that the light exiting from the second region enters, the wave plate layer causing the lights that have entered the third to sixth regions to exit as lights in the same polarized state; and a reflective layer that reflects the lights reflected by the first region and the second region. The directions of optical axes of the third region and the fifth region, or the fourth region and the sixth region, are perpendicular to each other.
