Abstract

A semiconductor light emitting element in which changes in light distribution characteristics due to inclination angle of side surfaces are suppressed. The semiconductor light emitting element includes a semiconductor structure having a light extracting surface as its upper surface; a reflecting layer disposed on side surfaces of the semiconductor structure; and a positive electrode and a negative electrode disposed on a lower surface of the semiconductor structure. Side surfaces of the semiconductor structure are inclined, expanding upward from the lower surface to the upper surface. At least a portion of each side surface includes a plurality of protrusions, a plurality of recesses, or a combination thereof.
