Abstract: 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.

Abstract: An organic EL device includes at least two light-emitting units and at least one intermediate electrode that are disposed between a lower electrode and an upper electrode, the at least one intermediate electrode being electrically connected to an external power source. The at least one intermediate electrode is disposed between the at least two light-emitting units. At least one of the at least one intermediate electrode consists of a first metal layer composed of a metal with a work function of 3 eV or lower and a second metal layer adjoining the first metal layer and composed of another metal with a work function of 4 eV or higher. The first and second metal layers have a total thickness of 15 nm or less. The first metal layer is adjacent to an anode side of the second metal layer, when a voltage is applied across the intermediate electrode and the electrode opposing the intermediate electrode.
