Abstract
Provided is a micro light emission element including a compound semiconductor in which an N-side layer, a light emission layer, and a P-side layer are laminated sequentially from a side of a light emitting surface, in which an N-electrode coupled to the N-side layer and a P-electrode coupled to the P-side layer are disposed on another surface opposite to the light emitting surface, the P-electrode is disposed on the light emission layer, the N-electrode is disposed in an isolation region which is a boundary region of the micro light emission element and isolates the light emission layer from a light emission layer of another micro light emission element, a surface of the N-electrode on a side of the other surface and a surface of the P-electrode on the side of the other surface are flush with each other, and the N-electrode and the P-electrode are both formed of a single interconnection layer.
