| 摘要 |
An organic electroluminescence device is disclosed. The device includes an anode, a cathode formed above the anode, a light-emitting layer containing an organic light-emitting material that is formed between the anode and the cathode, a hole-injecting layer on the anode that includes a hole-transporting material and an acceptor, and an electron-transporting suppressing stack between the hole-injecting layer and the light-emitting layer. The electron-transporting suppressing stack consists of multiple carrier-transporting layers, and forms energy barriers relative to electrons flowing from the light-emitting layer to the hole-injecting layer.
