Abstract: An organic electroluminescent device of which emission life may be improved. The organic electroluminescent device includes an anode, an emission layer, and an anode-side hole transport layer provided between the anode and the emission layer and including an anode-side hole transport material. An electron accepting material is doped in the anode-side hole transport layer. An intermediate hole transport material layer is provided between the anode-side hole transport layer and the emission layer and includes an intermediate hole transport material, and an emission layer-side hole transport layer is provided between the intermediate hole transport material layer and the emission layer and adjacent to the emission layer. The emission layer-side hole transport layer includes an emission layer-side hole transport material represented by the following Formula 1.
