Patent ID: 8835966

Claim:
A semiconductor light-emitting element which comprises: a substrate, a semiconductor layer formed on the substrate, wherein the semiconductor layer includes an n-type semiconductor layer, a light-emitting layer and a p-type semiconductor layer; an n-type electrode which is provided on an exposed surface of the n-type semiconductor layer, wherein the exposed surface is exposed by removing a part of the semiconductor layer, a transparent conductive film which is provided on the semiconductor layer, a p-type electrode which is provided on the transparent conductive film, and a light-reflecting layer which is provided between the semiconductor layer and the transparent conductive film, wherein at least a part of the light-reflecting layer overlaps with the p-type electrode when the light-reflecting layer is observed in planar view, wherein the p-type electrode comprises a pad portion and a linear portion which linearly extends from the pad portion and has an annular structure when the linear portion is observed in planar view, the n-type electrode exists in an inner area, which is surrounded by the linear portion, and exists on a straight line which goes through a center of the pad portion and a center of the semiconductor layer when the electrode is observed in planar view, a distance between the center of the n-type electrode and the center of the pad portion is greater than or equal to a distance between the center of the pad portion and the center of the semiconductor layer, the area of the light-reflecting layer is in a range of 30% to 200% based on the area of the p-type electrode, and a distance between an outer edge of the linear portion of the p-type electrode and an edge of the semiconductor layer is in a range of 30 to 120 μm.
