Abstract:
An organic electroluminescence device includes: a cathode; an anode; and an organic thin-film layer having one or more layers and provided between the anode and the cathode, in which the organic layer includes an emitting layer. The emitting layer includes a first host material, a second host material and a phosphorescent dopant material. The first host material is a compound represented by a formula (1A). The second host material is a compound represented by a formula (2A).
