Organic electroluminescent device and display using same

An organic electroluminescent device comprising:

• at least two or more emitting layers between an anode and a cathode, and
• an intermediate electrode layer being interposed between emitting layers,
• the intermediate electrode layer being a single layer or a multilayer structure, at least one of the layers comprising a semiconductive material and at least one of the layers comprising a donor that is an alkali metal and/or an alkaline earth metal,
• the semiconductive material comprising an acceptor that is at least one conductive oxide comprising a transition metal selected from the group consisting of NbOX, LaOx, NdOx, SmOx, EuOx, MoOx, WOx, OsOx, IrOx and PtOx, wherein x is 0.2 to 5;
• wherein the acceptor is the main constituent of the intermediate electrode layer and the ratio of donor to acceptor in the intermediate electrode layer is between 2:98 to 20:80 by weight.
