Abstract:
An organic electroluminescence device includes: an anode; a cathode; an emitting layer disposed between the anode and the cathode; and a hole transporting layer disposed between the anode and the emitting layer. The emitting layer contains a first compound represented by a formula (1) and a fluorescent second compound. The hole transporting layer contains a third compound represented by a formula (3). In the formula (1), Z 1  is represented by a formula (1a). A cyclic structure represented by a formula (1b) or (1c) may be fused to Z 1 . Each of X 1  and X 2  is an oxygen atom, a sulfur atom, NR A  or CR B R C .
