Organic light-emitting device employing doped hole transporting layer and/or hole injecting layer
摘要：
An organic light-emitting device including an anode, a cathode, an emission layer interposed between the anode and the cathode, and at least one of the hole injecting layer and the hole transporting layer interposed between the anode and the emission layer, wherein the at least one of the hole injecting layer and the hole transporting layer includes a host material, and a dopant material as an electron acceptor, wherein the dopant material has an electron affinity greater than that of the host material by at least 0.1 eV.
