Abstract:
An organic electroluminescent element includes a laminated body incorporating an anode substrate, an anode, at least one non-light emitting organic layer A exhibiting positive hole transportability, at least one light emitting organic layer B, at least one non-light emitting organic layer C exhibiting electron transportability, a cathode, and a cathode substrate in the sequence set forth. At least 80% by weight of the organic layer A and the organic layer C in the laminated body is formed via a wet process, and the laminated body is made with an adhesion process between the organic layer A and the organic layer B, or between the organic layer B and the organic layer C.
