Abstract:
1. A semiconductor light emitting element, comprising: a semiconductor multilayer structure comprising a first conductive type layer, a second conductive type layer, and a light emitting layer sandwiched between the first conductive type layer and the second conductive type layer; a first transparent electrode formed on the second conductive type layer; a reflecting layer formed on the first transparent electrode, and having a smaller area than the first transparent electrode; a second transparent electrode formed on the first transparent electrode so as to cover the reflecting layer; and a pad electrode formed on the second transparent electrode and in a region above the reflecting layer, wherein light emitted from the light emitting layer is extracted in a direction from the light emitting layer to the second conductive type layer, wherein the first and second transparent electrodes comprise a conductive metal oxide, wherein, in a plan view, the reflecting layer extends beyond a boundary of the pad electrode, wherein the reflecting layer comprises a metal and a transparent layer disposed on a bottom surface of the metal, wherein the transparent layer is disposed on an entirety of each of an upper surface of the metal, the bottom surface of the metal, and side surfaces of the metal, and wherein edges of the metal are aligned with edges of the pad electrode.
