摘要：
An organic electroluminescent device (1) comprising: an anode (20), a cathode (70) and a plurality of layers comprising at least a hole-injecting-transporting layer (30) in contact with the anode (20) and an emitting layer. (40), the plurality of layers being provided between the anode (20) and the cathode (70), a difference in ionization potential between the hole-injecting-transporting layer (30) and the anode (20) being more than 0.7 eV.
