Abstract

An organic electroluminescent device, having a cathode, an indium-tin-oxide anode, an emitting layer, a hole transport layer, an electron transport layer, a hole injecting layer and a intermediate layer. The emitting layer is located between the cathode and the indium-tin-oxide anode. The hole transport layer is located between the emitting layer and the indium-tin-oxide anode, the electron transport layer is located between the emitting layer and the cathode, the hole injecting layer is located between the hole transport layer and the indium-tin-oxide anode, and the intermediate layer is located between the hole injecting layer and the hole transport layer.
