Patent ID: 8866382

Claim:
A light-emitting device, comprising: a supporting substrate; an organic electroluminescent element comprising a first electrode, one or more organic electroluminescent layers and a second electrode that are layered in this order on the supporting substrate; a first extracting electrode for electrically connecting to an external electric power supply, that is integrally formed and extended from the first electrode on the supporting substrate; a second extracting electrode for electrically connecting to an external electric power supply, that is arranged away from the first electrode and the first extracting electrode on the supporting substrate; a connecting electrode that is integrally formed and extended from the second electrode and that is connected to the second extracting electrode, on the supporting substrate; and a first heat-dissipating member that is integrally formed and extended from the second electrode and that is insulated electrically from the first electrode and the first extracting electrode, on the supporting substrate.
