Patent ID: 8017253

Claim:
An organic electroluminescent element comprising: a substrate; a first electrode layer formed on the substrate; an organic electroluminescent layer formed on the first electrode layer; and a second electrode layer formed on the organic electroluminescent layer, wherein a photocatalyst containing layer containing a photocatalyst, a characteristic providing agent, and a light emission characteristic improving material having a function of improving an activation of the photocatalyst and a light emission characteristic of the organic electroluminescent layer so as to have a characteristic of the characteristic providing agent changed by an action of the photocatalyst accompanied by an energy irradiation is formed at any position between the substrate and the second electrode layer; and the light emission characteristic improving material is a silver salt of a fluorine or a silver salt of an acid selected from the group consisting of phenols, enols, thiophenols, imides, oximes, clathrate compounds, a chloric acid and a perchloric acid.
