Abstract:
An organic electroluminescence device includes an anode, a cathode, and an emitting region disposed between the anode and the cathode, in which the emitting region includes a first emitting layer and a second emitting layer, the first emitting layer contains a first compound represented by a formula below, and the second emitting layer contains a second compound. At least one of R101 to R112 in the formula (100A), L101 or Ar101 in the formula (100B) has at least one deuterium atom. When only L101 has at least one deuterium atom, the at least one deuterium atom is bonded to a ring that is of rings forming L1 and directly bonded to a benz[a]anthracene ring in the formula (100A).
