Abstract:
1. An organic electroluminescence device comprising one or a plurality of organic thin film layers comprising at least an emitting layer between an anode and a cathode; and at least one layer of the organic thin film layers comprises an aromatic amine derivative represented by the following formula (1): wherein Ar Ar L is a group represented by the following formula (A) or (B); L: wherein X 1 and X 2 are independently a substituent, 1 and m are independently an integer of 0 to 3, and R 1 is a substituted or unsubstituted alkylene group having 1 to 3 carbon atoms; and Ar an aromatic amine derivative in which Ar the emitting layer comprises the aromatic amine derivative and a compound represented by the following formula (2a) which has an anthracene skeleton; wherein Ar 11 and Ar 12 are independently a group derived from a substituted or unsubstituted aromatic ring having 6 to 20 carbon atoms, and R 11 to R 18 are independently a group selected from a hydrogen atom, a substituted or unsubstituted aryl group having 6 to 50 carbon atoms, a substituted or unsubstituted heteroaryl group having 4 to 50 carbon atoms, a substituted or unsubstituted alkyl group having 1 to 50 carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 50 carbon atoms, a substituted or unsubstituted alkoxy group having 1 to 50 carbon atoms, a substituted or unsubstituted aralkyl group wherein the aryl part has 6 to 50 carbon atoms, and the alkyl part has 1 to 50 carbon atoms, a substituted or unsubstituted aryloxy group having 5 to 50 carbon atoms, a substituted or unsubstituted arylthio group having 5 to 50 carbon atoms, a substituted or unsubstituted alkoxycarbonyl group wherein the alkyl part has 1 to 50 carbon atoms, a substituted or unsubstituted silyl group, a carboxyl group, a halogen atom, a cyano group, a nitro group and a hydroxyl group.
