    摘要: An organic light emitting device includes a mixed region composed of a mixture of a hole transport material and an electron transport material, one of which is an emitter. The organic light emitting device also includes at least one of a hole transport material region and an electron transport material region on the mixed region. An anode contacts the hole transport material region or the mixed region. A cathode contacts the electron transport material region or the mixed region. The hole transport material region and/or the electron transfer material region can be formed with a plurality of layers.
