Organic electroluminescence device.

摘要

An organic electroluminescence device having a light emitting layer or a light emitting layer and a charge transport layer disposed between a pair of electrodes at least one of which is transparent or semi-transparent, the light emitting layer comprising a conjugated polymer having a repeating unit of the general formula (1): -Ar1 - CH = CH- (1) where Ar1 represents an aromatic hydrocarbon group of 6 to 14 carbon atoms which is unsubstituted or substituted by one or two hydrocarbon or alkoxy groups of 1 to 22 carbon atoms. The conjugated polymer may also be used as a charge transport material or a buffer layer to an electrode, in an electroluminescence device.
