Abstract:
An organic electroluminescence device includes an anode, an emitting layer and a cathode, in which the emitting layer includes a first compound, a second compound and a third compound. The first compound is a delayed fluorescent compound. The first compound has an energy gap T77K at 77 [K] larger than an energy gap T77K at 77 [K] of the second compound. The third compound has an energy gap T77K at 77 [K] larger than the energy gap T77K at 77 [K] of the second compound. The second compound has a fused ring structure represented by a formula (2) below and has eight or less rings in total.
