Claim:
1. A light-emitting diode comprising a compound semiconductor layer provided on a substrate and comprising a light-emitting layer and an etching stop layer in this order; an ohmic contact electrode provided between the substrate and the compound semiconductor layer; an ohmic electrode provided on an opposite side of the compound semiconductor layer with respect to the substrate; a surface electrode comprising a branch section provided so as to cover a surface of the ohmic electrode and a pad section coupled to the branch section; and a current-blocking portion provided between an under-pad light-emitting layer arranged in an area of the light-emitting layer that overlaps the pad section in a planar view and a light-emitting layer arranged in an area except an area that overlaps the pad section in a planar view, to prevent a current being supplied to the under-pad light-emitting layer, wherein the current-blocking portion has an annular shape in a planar view so as to surround the under-pad light-emitting layer, and an end face of the current-blocking portion in the thickness direction of the light-emitting diode furthest from the substrate is provided to contact with the etch stop layer.
