ORGANOLUMINESCENT DEVICE

摘要

The present invention relates to an organic electroluminescence device. According to the present invention, the organic electroluminescence device includes an anode; a cathode; and at least one organic layer formed between the anode and the cathode. The work function of the cathode is lower than the HOMO energy level of an adjacent organic layer.
