Abstract:
1. An organic electroluminescence device in which an organic thin film layer comprising a single layer or plural layers and comprising a light emitting layer is interposed between a cathode and an anode, wherein at least one layer in the organic thin film layer comprises, as a single component or a mixed component, an aromatic amine derivative represented by the following Formula (1): wherein, L is a linkage group comprising a substituted or non-substituted arylene group having 5 to 50 ring atoms or a linkage group obtained by combining plural substituted or non-substituted arylene groups having 5 to 50 ring atoms with single bonds, oxygen atoms, sulfur atoms, nitrogen atoms or saturated or unsaturated divalent aliphatic hydrocarbon groups having 1 to 20 ring atoms, wherein the arylene group having 5 to 50 ring atoms is a member selected from the group consisting of 1,4-phenylene, 1,2-phenylene, 1,3-phenylene, 1,4-naphthylene, 2,6-naphthylene, 1,5-naphthylene, 9,10-anthyranylene, 9,10-phenanthrenylene, 3,6-phenanthrenylene, 1,6-pyrenylene, 6,12-chrysenylene, 1,1′-biphenylene, 4,4′-biphenylene, 3,3′-biphenylene, 2,2′-biphenylene, 2,7-fluorenylene, 2,5-thiophenylene, 2,5-silolylene, 2,5-oxadiazolylene, and terphenylene; A is a diarylamino group represented by the following Formula (2): B is a diarylamino group represented by the following Formula (3); provided that A is not the same as B: wherein Ar Ar wherein R wherein R x is an integer of 0 to 3; y is an integer of 0 to 2; and R wherein Ar R s, q and r each are an integer of 0 to 2; R provided that Ar
