An organic electroluminescent device is provided and includes: a pair of electrodes; and at least one organic layer between the pair of electrodes, the at least one organic layer including a light-emitting layer. The at least one organic layer includes at least one layer containing an indole derivative represented by formula (1), and the light-emitting layer includes a platinum complex phosphorescent material having a tetradentate ligand. R101, R102, R103, R104, R105, R106 and R107 each independently represents a hydrogen atom or a substituent, provided that R102 and R103 are not bonded to each other to form an aromatic condensed ring.
