An electroluminescent device having an organic electroluminescent layer

摘要

The pixel device uses a pair of thin-film transistors as active matrix addressing elements and organic electroluminescent thin-films as the emission medium. An insulating substrate carries the thin-film transistors, a capacitor and an overlying passivation layer, with a tapered opening over which an organic electroluminescent layer (82) is applied. A cathode layer directly overlying the electroluminescent layer is pref. formed as a continuous layer of a low work function material.
