Patent ID: 11624973

Abstract:
A light emitting device includes a substrate, a first semiconductor layer provided to the substrate, a laminated structure disposed at an opposite side to the substrate of the first semiconductor layer, and including a plurality of columnar parts, a first electrically-conductive layer as a surface layer at laminated structure side in the first semiconductor layer, and a second electrically-conductive layer opposed to the first electrically-conductive layer via the laminated structure, wherein the columnar part includes a light emitting layer configured to emit light, a second semiconductor layer which is disposed between the light emitting layer and the first electrically-conductive layer, and a third semiconductor layer disposed between the light emitting layer and the second electrically-conductive layer, concavo-convex shapes are formed on a surface of the first electrically-conductive layer, an insulating layer is disposed on the first electrically-conductive layer, and electrode layers are disposed so as to cover an area where the insulating layer is disposed, and some of the concavo-convex shapes.
