<P>PROBLEM TO BE SOLVED: To provide a nitride gallium based compound semiconductor light-emitting element, provided with a reflection-type positive electrode having satisfactory extraction of light emission and increasing the efficiency of wavelength conversion of a phosphor. <P>SOLUTION: The semiconductor light-emitting element is provided with a nitride based gallium compound semiconductor chip and a phosphor, and converts the emission wavelength from the semiconductor chip using the phosphor. A concave groove is formed from a light-extracting surface of this semiconductor chip to a light-emitting layer. This semiconductor light-emitting element has the phosphor filled inside the concave groove. <P>COPYRIGHT: (C)2007,JPO&INPIT |
