ORGANIC ELECTROLUMINESCENCE ELEMENT AND ILLUMINATION DEVICE |
摘要 |
An object is providing an organic electroluminescence element and an illumination device in which a driving voltage does not increase even when a high-productivity sputtering method is used to form a transparent conductive layer of the organic electroluminescence element of a top or top-and-bottom emission type, and hence which has an improved driving voltage. The organic electroluminescence element includes at least a light emitting layer and a transparent conductive layer. Between the light emitting layer and the transparent conductive layer, a transparent protective layer is disposed. The light emitting layer contains a phosphorescence emitting compound. The transparent protective layer contains a metal oxide. The metal oxide is a molybdenum (VI) oxide, a rhenium (VI) oxide or a nickel (II) oxide in an oxygen deficient state.
