Abstract:
A light emitting device includes an organic light emitting layer disposed on a substrate and first and second electrodes between which the organic light emitting layer is disposed on the substrate. The second electrode is formed on the opposite side to the substrate of the organic light emitting layer. A buffer layer is disposed between the second electrode and the organic light emitting layer and is mainly made of oxide having a smaller quantity of oxygen generated in decomposition upon formation of the buffer layer than that of oxygen generated in decomposition upon formation of the second electrode. Further, the substrate is made of metal.
