Abstract:
An organic electroluminescence device is provided. The device comprises an anode base layer (110), a hole injection layer (120) on the anode base layer (110), a light emitting layer (130) on the hole injection layer (120), and a cathode electrode layer (140) on the light emitting layer (130). The material of the hole injection layer (120) is metal oxide or thiophene type compound. The hole injection layer (120) has advantages of improving the recombination probability of electron-hole and not being easily oxidized, so that the efficiency of the organic electroluminescence device is increased and the service life is prolonged. A method for manufacturing the organic electroluminescence device is also provided.
