摘要：
An organic electroluminescent device comprising at least two organic layers including a light emitting layer (5) and a delayed fluorescent exciplex layer (7) containing a donor compound and an acceptor compound, between a pair of electrodes (2, 9) is highly efficient in formation of a singlet excited state and enables high light emission efficiency.
