<P>PROBLEM TO BE SOLVED: To provide a semiconductor light-emitting element capable of uniformizing a distribution of an injection current density, suppressing a excessive injection current density and having high performance. <P>SOLUTION: The semiconductor light-emitting element comprises: a laminate structure which has a first semiconductor layer, a second semiconductor layer and a light-emitting layer provided between the first semiconductor and the second semiconductor layers, and in which the second semiconductor layer and the light-emitting layer are selectively removed to expose a part of the first semiconductor layer; a first electrode contacting with a part of the first semiconductor layer; a second electrode contacting with the second semiconductor layer and having high transmissivity; and a pad layer provided on the side opposite to the light-emitting layer of the second semiconductor layer, electrically connected to the second electrode, and having lower transmissivity for light than that of the second electrode. The conductivity of the second electrode continuously decreases along a direction from the pad layer to the first electrode. <P>COPYRIGHT: (C)2012,JPO&INPIT |
