Abstract:
An organic electroluminescent device includes an anode, an emission layer, an anode-side hole transport layer on the anode and the emission layer, the anode-side hole transport layer including an anode-side hole transport material and the anode-side hole transport layer being doped with an electron accepting material, an intermediate hole transport material layer between the anode-side hole transport layer and the emission layer, the intermediate hole transport layer including an intermediate hole transport material, and an emission layer-side hole transport material between the intermediate hole transport material layer and the emission layer and adjacent to the emission layer, the emission layer-side hole transport material layer including an emission layer-side hole transport material represented by the following General Formula (1): where Ar1, Ar2, Ar3, Ar4, L1, and L2 are as defined in the specification.
