    摘要: An organic electroluminescent device (1) including an anode (2), a cathode (6), and at least a first layer (3), a second layer (4), and a third layer (5) provided between the anode (2) and the cathode (6) in that order from the anode side. At least one of the first to third layers (3), (4), and (5) includes a phosphorescent compound. At least one of the first to third layers (3), (4), and (5) is an emitting layer. At least three compounds respectively forming the first layer (3), the second layer (4), and the third layer (5) other than the phosphorescent compound are compounds of the following formula (1). wherein R1 to R7 each represent a hydrogen atom or a substituent, provided that adjacent substituents may form a ring.
