Abstract
A polymer type organic EL element is improved in terms of the stability and the efficiency and intensity of light emission. A carrier injection layer made of discotic liquid crystal or smectic liquid crystal having an electron resonance structure is interposed between a polymer layer and an electrode.
Claims5
An organic electroluminescence element comprising a substrate, a pair of electrodes, an organic polymer luminescent layer arranged between said pair of electrodes, and a liquid crystal layer arranged between said pair of electrodes, said organic polymer luminescent layer emitting light as an electric current flows between said electrodes,
- wherein said liquid crystal layer is arranged so that said liquid crystal layer is in contact with a surface of said organic polymer luminescent layer, said surface having been subjected to a rubbing treatment.
