| Zusammenfassung: | In a nitride semiconductor light emitting element, a light transmitting substrate has an upper surface on which a nitride semiconductor layer including at least a light emitting layer is formed. On the upper surface of the light transmitting substrate, recess regions and rise regions are formed. One of each of the recess regions and each of the rise regions is formed by a polygon having at least one apex having an interior angle of 180° or greater when viewed in a planar view. The other of each of the recess regions and each of the rise regions is formed not to be connected to one another in a straight line when viewed in a planar view. A nitride semiconductor light emitting element having such a configuration has excellent light extraction efficiency and can be manufactured at a moderate cost. |
