, (2013/06/27)
An organic electroluminescence device (1) includes: an anode (3); a cathode (4) being opposed to the anode (3); and an emitting layer (5) being provided between the anode (3) and the cathode (4). The emitting layer (5) includes a host material and a phosphorescent dopant material. The host material includes a monoamine derivative represented by a formula (1A) below. In the formula (1A), each of Ar1, Ar2 and Ar4 is a substituted or unsubstituted aryl group or heteroaryl group, Ar3 is a substituted or unsubstituted arylene group or heteroarylene group, n is an integer of 0 to 5, Ar3 may be mutually the same or different when n is 2 or more, and at least one of Ar1, Ar2 and Ar4 is a group derived from a fused aromatic hydrocarbon skeleton having 3 or more rings.
