Abstract:
1. A semiconductor light emitting device comprising: a laminated body including a first semiconductor layer, a second semiconductor layer, and a light emitting layer provided between the first semiconductor layer and the second semiconductor layer; a first electrode provided on a first major surface of the laminated body and connected to the first semiconductor layer; and a second electrode provided on the first major surface of the laminated body and connected to the second semiconductor layer, wherein the first electrode includes: a first region provided on the first semiconductor layer and including a first metal film that is in direct contact with the first semiconductor layer; and a second region provided on the first semiconductor layer and including a second metal film that is in direct contact with the first semiconductor layer, the second metal film having a higher reflectivity for light emitted from the light emitting layer than the first metal film and having a higher contact resistance with respect to the first semiconductor layer than the first metal film, and wherein the second electrode includes: a third metal film that is in direct contact with the second semiconductor layer; and a fourth metal film that is in direct contact with the second semiconductor layer, the fourth metal film having a lower reflectivity for the light emitted from the light emitting layer than the third metal film.
