<P>PROBLEM TO BE SOLVED: To provide a white light emitting element having almost no color unevenness. <P>SOLUTION: The white light emitting element includes: a semiconductor layer 104 which has an n-type semiconductor layer 101, a p-type semiconductor layer 103, and a light-emitting layer 102 sandwiched between the n-type semiconductor layer 101 and the p-type semiconductor layer 103 so as to generate light and in which one of the main faces is a light-emitting face; a phosphor containing layer 114 containing a phosphor, which absorbs light generated by the light-emitting layer 102 so as to emit a fluorescence, and provided on the face, facing the light-emitting face, of the main faces of the semiconductor layer; and a reflecting layer 115 provided on the face, facing the face provided with the semiconductor layer 104, of the faces of the phosphor containing layer 114. Irregularities are formed on an interface between the reflecting layer 115 and the phosphor containing layer 114. <P>COPYRIGHT: (C)2010,JPO&INPIT |
