Abstract:
A light-emitting element includes a semiconductor laminated structure including a first semiconductor layer of a first conductivity type, a second semiconductor layer of a second conductivity type different from the first conductivity type and an active layer sandwiched by the first and second semiconductor layers, a first electrode on one surface side of the semiconductor laminated structure, a conductive reflective layer on an other surface side of the semiconductor laminated structure for reflecting light emitted from the active layer, a contact portion partially formed between the semiconductor laminated structure and the conductive reflective layer and being in ohmic contact with the semiconductor laminated structure, and a second electrode on a part of a surface of the conductive reflective layer on the semiconductor laminated structure without contacting the semiconductor laminated structure for feeding current to the contact portion.
