LIGHT EMITTING ELEMENT AND DISPLAY DEVICE

Abstract:

A light emitting element includes a light emitting portion, an intermediate layer covering the light emitting portion, an optical path control unit disposed on or above the intermediate layer, and a coating layer covering at least the optical path control unit. Light emitted from the light emitting portion passes through the intermediate layer, and enters then exits from the optical path control unit. The coating layer includes first and second coating layer. The first coating layer covers a part of an outer surface of the optical path control unit on the intermediate layer side. The second coating layer covers the first coating layer and the rest of the outer surface of the optical path control unit. Values of refractive indices of materials constituting the optical path control unit, the first coating layer, and the second coating layer are different from each other.
