摘要：
An organic light emitting device comprises a light emitting layer comprising a light emitting polymer; and an electron transporting layer on the light emitting layer and comprising an electron transporting material and an n-donor material. The electron transporting layer comprises at least 20 percent by weight of the n-donor material. By using an electron transporting layer comprising at least 20 percent by weight of the n- donor material it is possible to realise devices with an electron transporting layer having a thickness of less than 20nm.
