Abstract:
1. A group III nitride semiconductor light-emitting device comprising: a substrate; a single-crystal group III nitride semiconductor layer which is formed on the substrate; a semiconductor layer which is formed on the single-crystal group III nitride semiconductor layer and in which an n-type semiconductor layer, a light-emitting layer and a p-type semiconductor layer are sequentially layered; and a light-transmitting electrode which is formed on the p-type semiconductor layer, wherein an insulation layer is formed on at least a part of the p-type semiconductor layer, and the light-transmitting electrode is formed to cover the insulation layer; on a surface of the light-transmitting electrode, a positive electrode bonding pad is provided above the insulation layer provided on the p-type semiconductor layer; and a sheet resistance of the n-type semiconductor layer is lower than a sheet resistance of the light-transmitting electrode.
