Patent ID: 7239084

Claim:
An organic electroluminescence device comprising: a semiconductor substrate, at least part of the semiconductor substrate forming a Peltier element including a heat absorbing portion and a heat radiating portion; and an organic electroluminescence element arranged on or above the semiconductor substrate, wherein the organic electroluminescence element is arranged so that heat resistance between the organic electroluminescence element and the heat absorbing portion is less than heat resistance between the organic electroluminescence element and the heat radiating portion, and light emitted from the organic electroluminescence element exits from a side facing away from the semiconductor substrate, wherein the Peltier element includes a heat absorbing electrode formed at the heat absorbing portion and a heat radiating electrode formed at the heat radiating portion, and the heat absorbing electrode of the Peltier element also serves as an electrode of the organic electroluminescence element or is directly connected to an electrode of the organic electroluminescence element.
