Patent ID: 7981523

Claim:
An organic electroluminescence device comprising: a cathode; an anode; and one or multiple organic thin film layers including at least a light-emitting layer, the one or multiple organic thin film layers being interposed between the cathode and the anode, wherein the light-emitting layer comprises: an anthracene derivative; and an aromatic amine derivative represented by the following general formula (1): where: A 1 , A 2 , and R 1 each independently represent a hydrogen atom, a substituted or unsubstituted alkyl group having 1 to 50 carbon atoms, a substituted or unsubstituted aryl group having 5 to 50 carbon atoms, a substituted or unsubstituted aralkyl group having 6 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 aryloxy group having 5 to 50 carbon atoms, a substituted or unsubstituted arylamino group having 5 to 50 carbon atoms, a substituted or unsubstituted alkylamino group having 1 to 20 carbon atoms, a substituted or unsubstituted heterocyclic group having 5 to 50 carbon atoms, or a halogen atom, and A 1 and A 2 may bind to each other to form a saturated or unsaturated ring provided that chrysene is excluded when A 1 and A 2 form a saturated or unsaturated ring; a and b each represent an integer of 0 to 5, and multiple A 1 s and multiple A 2 s may be identical to or different from each other, and may bind to each other to form a saturated or unsaturated ring when a and b each represent 2 or more; p represents an integer of 2, and groups in ( ) may be identical to or different from each other, provided that the groups in ( ) are substituted at the 1- and 6- positions of the pyrene core; q represents an integer of 0 to 9, and multiple R 1 s may be identical to or different from each other when q represents 2 or more; and X 1 represents a substituted or unsubstituted arylene group having 5 to 50 carbon atoms.
