Light emitting element, method of manufacturing light emitting element, and method of manufacturing display device

Abstract

A method of manufacturing a light emitting element, comprises placing a plurality of mask patterns on a substrate, forming first patterns on the substrate through the plurality of mask patterns, the first patterns recessed from an upper surface of the substrate, forming an undoped semiconductor layer on the substrate on which the first patterns are formed, etching the undoped semiconductor layer, forming a first semiconductor layer on the undoped semiconductor layer, forming an active layer on the first semiconductor layer, forming a second semiconductor layer on the active layer, and forming an electrode layer on the second semiconductor layer, wherein the undoped semiconductor layer includes second patterns recessed from a lower surface of the undoped semiconductor layer.
