Abstract

An organic electroluminescent device 1 comprising, an emitting layer (50) and an electron-transporting layer (60) between a cathode (80) and an anode (20), the electron-transporting layer (60) comprising a compound represented by formula (1), the emitting layer (50) comprising a host material which is a compound with an energy gap of 2.8 eV or less represented by formula (2) and a dopant which is an indenoperylene derivative, €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒA-B€ƒ€ƒ€ƒ€ƒ€ƒ(1) wherein A is an aromatic hydrocarbon group with three or more carbocycles and B is a substituted or unsubstituted heterocyclic group, €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒX-(Y) n €ƒ€ƒ€ƒ€ƒ€ƒ(2) wherein X is a condensed aromatic ring group with three or more carbocycles, Y is a group selected from substituted or unsubstituted aryl, substituted or unsubstituted diarylamino, substituted or unsubstituted arylalkyl and substituted or unsubstituted alkyl groups, and n is an integer of 1 to 6, provided that Ys may be the same or different when n is 2 or more.
