The OLED has electrodes between which is a fullerene charge transporting layer and an electroluminescent material layer. The OLED has in order an anode, a fullerene hole transporting layer, the electroluminescent layer, a fullerene electron transporting layer and a cathode. The hole transporting layer may have one or more adjacent hole transporting layers and the electron transporting layer may have one or more adjacent electron transporting layers. The fullerene may be mixed with polymers and/or doped with metal. |
