Abstract:
1. A light emitting element, comprising: a semiconductor laminate structure comprising a first semiconductor layer of a first conductivity type, a light emitting layer, and a second semiconductor layer of a second conductivity type different from the first conductivity type, a part of the second semiconductor layer and the light emitting layer being removed to expose a part of the first semiconductor layer; a first reflecting layer on the semiconductor laminate structure and comprising an opening, the opening being formed in the exposed part of the first semiconductor layer; a transparent wiring electrode for carrier injection into the first semiconductor layer or the second semiconductor layer through the opening; a second reflecting layer formed on the transparent wiring electrode and covering a part of the opening so as to reflect light emitted from the light emitting layer and passing through the opening back to the first semiconductor layer; a contact electrode comprising a transparent conducting layer, one surface of which contacts the transparent wiring electrode and an other surface of which contacts the first semiconductor layer or the second semiconductor layer; an insulating layer formed in between the first reflecting layer and the second reflecting layer and/or in between the first reflecting layer and the transparent wiring electrode; and a metallic wiring electrode formed at a region on the first reflecting layer and except the opening, and electrically connected to the transparent wiring electrode.
