Abstract:
An organic electroluminescent device including: an anode, a cathode, an emitting layer formed of an organic compound and interposed between the cathode and the anode, and two or more layers provided in a hole-injecting/hole-transporting region between the anode and the emitting layer; of the layers which are provided in the hole-injecting/hole-transporting region, a layer which is in contact with the emitting layer containing a compound represented by the formula (1); and of the layers which are provided in the hole-injecting/hole-transporting region, a layer which is interposed between the anode and the layer which is in contact with the emitting layer containing an amine derivative represented by the formula (2).
