Abstract

Provided is an organic electroluminescence device, including: an anode; a cathode; and organic thin film layers provided between the anode and the cathode, in which: the organic thin film layers have a light emitting layer, and have a hole injecting layer and a hole transporting layer, or a hole injecting/transporting layer on a side which is closer to the anode than the light emitting layer is; the hole injecting layer or the hole injecting/transporting layer contains an aromatic amine derivative having a specific substituent, and the hole transporting layer or the hole injecting/transporting layer contains an aromatic amine derivative having a specific substituent.
