Patent ID: 8455886

Claim:
A light emitting device comprising: a GaN-based LED chip, said GaN-based LED chip being flip-chip mounted, and comprising a light-transmissive substrate, a GaN-based semiconductor layer disposed on said light-transmissive substrate, and a negative electrode partially disposed on a backside of said light-transmissive substrate, said light-transmissive substrate having electrical conductivity, and said GaN-based semiconductor layer having a laminate structure comprising an n-type layer, a light emitting layer and a p-type layer in this order from a light-transmissive substrate side, wherein a positive electrode is disposed on the p-type layer, said electrode comprising a light-transmissive electrode including an oxide semiconductor, and a positive contact electrode electrically connected to said light-transmissive electrode, and wherein an area of said positive contact electrode is smaller than an area of said light-transmissive electrode.
