<P>PROBLEM TO BE SOLVED: To solve a problem that, in a light extraction surface of an epitaxial grown semiconductor layer, the transmitted light of light within an optimum angle is restricted to be low by Fresnel coefficient, therefore, the efficiency of light extraction of the light Q within the optimum angle becomes low. <P>SOLUTION: A semiconductor alternating laminate 101 is provided in which semiconductor layers 1011, 1012, ... having a different refractive index are alternately laminated and formed on the light extraction surface of light-emitting semiconductor layers 11-14 that form a light-emitting part. The semiconductor alternating laminate 101 performs an antireflection function. <P>COPYRIGHT: (C)2010,JPO&INPIT |
