Patent ID: 8779441

Claim:
A semiconductor light emitting element comprising: a laminated semiconductor layer that is formed on a substrate and in which a first semiconductor layer having a first conductivity type, a light emitting layer, and a second semiconductor layer having a second conductivity type different from the first conductivity type are laminated; a first electrode that is formed on a surface of the first semiconductor layer in the laminated semiconductor layer, and that has a first opening used for electrical connection with an outside; a second electrode that is formed on a surface of the second semiconductor layer, and that has a second opening used for electrical connection with the outside, the surface of the second semiconductor layer being exposed by cutting off a part of the laminated semiconductor layer; and a protecting layer disposed on the laminated semiconductor layer, wherein, the first and second openings are formed in the protecting layer to expose the first and second electrodes, respectively, the first opening has a concave arc portion opposite a convex arc portion of the second opening, the arc portion of the first opening is formed to keep an approximately equal distance from an outer edge portion of the second opening in a planar view, and an area of the first opening is at least 30% of a surface area of the first electrode.
