1. A light emitting element, comprising:
a first semiconductor layer;
an active layer on a surface of the first semiconductor layer;
a second semiconductor layer on the active layer;
an insulating film to enclose an outer periphery of each of the first semiconductor layer, the active layer, and the second semiconductor layer; and
an electrode layer on the second semiconductor layer,
wherein the first semiconductor layer comprises a first area that is covered by the insulating film, and a second area that is not covered by the insulating film,
wherein a perimeter of the outer periphery of the first semiconductor layer in the first area and a perimeter of an outer periphery of the first semiconductor layer in the second area are different from each other,
wherein the perimeter of the outer periphery of the first semiconductor layer in the second area is substantially equal to a perimeter of an outer periphery of the insulating film in the first area,
wherein the electrode layer comprises a first electrode layer on the second semiconductor layer, and a second electrode layer on the first electrode layer,
wherein the first electrode layer and the second electrode layer comprise different materials, and
wherein the first electrode layer comprises an ohmic layer in which Be is diffused, and the second electrode layer comprises a transparent metal oxide.
