<p><P>PROBLEM TO BE SOLVED: To provide a nitride semiconductor light emitting element which improves the catastrophic optical damage (COD) level after aging. <P>SOLUTION: In a nitride semiconductor light emitting element, a coat film is formed on a light emission part. In the nitride semiconductor light emitting element, the light emission part is formed by a nitride semiconductor, and the coat film is made of oxynitride of aluminium. The content of oxygen differs in the thickness direction of the nitride semiconductor light emitting element. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
