Abstract:
1. A semiconductor light emitting element comprising: a semiconductor layer including a light emitting layer that emits light by current flow, wherein the semiconductor layer has a semiconductor side surface including a first semiconductor side surface extending along a first direction and a second semiconductor side surface extending along a second direction intersecting the first direction, a semiconductor top surface, and a semiconductor bottom surface, the semiconductor top surface and the semiconductor bottom surface being connected with the semiconductor side surface and facing each other, on the first semiconductor side surface, a plurality of first depressing portions, each of which extends along a third direction proceeding from the semiconductor bottom surface toward the semiconductor top surface and depresses toward an inside of the semiconductor layer, and a plurality of first projecting portions, each of which extends along the third direction and projects toward an outside of the semiconductor layer compared to the first depressing portions are provided in an alternate arrangement along the first direction, on the second semiconductor side surface, a plurality of second depressing portions, each of which extends along the third direction and depresses toward the inside of the semiconductor layer, and a plurality of second projecting portions, each of which extends along the third direction and projects toward the outside of the semiconductor layer compared to the second depressing portions are provided in an alternate arrangement along the second direction, and projections and depressions formed on the first semiconductor side surface by the first depressing portions and the first projecting portions and projections and depressions formed on the second semiconductor side surface by the second depressing portions and the second projecting portions are different in shape.
