Patent ID: 8217570

Claim:
An organic electroluminescence device in which an organic thin film layer comprising an electron injecting layer and/or an electron transporting layer, and a light emitting layer is interposed between a cathode and an anode, wherein the electron injecting layer and/or the electron transporting layer comprise at least one anthracene derivative represented by the following formula (1): wherein R 1 to R 3 each independently represent a hydrogen atom, a halogen atom, a substituted or non-substituted aliphatic hydrocarbon group having 1 to 40 carbon atoms, a substituted or non-substituted aryl group having 5 to 60 carbon atoms, or a substituted or non-substituted heteroaryl group having 3 to 60 carbon atoms, with the proviso that R 1 and R 2 do not simultaneously represent a hydrogen atom; L 1 represents a single bond, a substituted or non-substituted divalent aliphatic hydrocarbon group having 1 to 40 carbon atoms, a substituted or non-substituted arylene group having 5 to 60 carbon atoms, or a substituted or non-substituted heteroarylene group having 3 to 60 carbon atoms; and HAr represents a substituted or non-substituted heteroaryl group which has 3 to 60 carbon atoms and comprises a nitrogen-containing six-membered ring.
