Manufacturing method for forming an inorganic light emitting element having a low surface roughness

Abstract

Provided are a light emitting device, a method for manufacturing same, and a display device including the light emitting device. The method for manufacturing the light emitting device comprises the steps of: preparing a lower substrate including a substrate and a buffer semiconductor layer formed on the substrate, forming an element rod by forming a separating layer disposed on the lower substrate, forming a first conductivity type semiconductor layer, an active material layer, and a second conductivity type semiconductor layer on the separating layer, and etching the first conductivity type semiconductor layer, the active material layer, the second conductivity type semiconductor layer, and the separating layer in a direction perpendicular to the lower substrate, forming a first insulating layer surrounding an outer circumferential surface of the element rod, forming a second insulating layer surrounding an outer circumferential surface of the first insulating layer and separating the element rod from the lower substrate to form a light emitting element.
