In an organic electroluminescence device including an anode, a hole injecting layer, an emitting layer, an electron transporting layer and a cathode, the hole injecting layer contains poly(alkylene dioxythophene) and at least one type of fluorine-containing colloid-forming polymer acids. The electron transporting layer contains a nitrogen-containing heterocycle derivative represented by a formula (1) below.
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒHAr-L-Ar 1 -Ar 2 €ƒ€ƒ€ƒ€ƒ€ƒ(1)
(In the formula: HAr represents a substituted or unsubstituted nitrogen-containing heterocycle group having 3 to 40 carbon atoms; L represents, a single bond, a substituted or unsubstituted arylene group having 6 to 60 carbon atoms, a substituted or unsubstituted heteroarylene group having 3 to 60 carbon atoms, or a substituted or unsubstituted fluorenylene group; Ar 1 represents a substituted or unsubstituted divalent aromatic hydrocarbon group having 6 to 60 carbon atoms; and Ar 2 represents a substituted or unsubstituted aryl group having 3 to 60 carbon atoms.) |
