An organic EL device including a cathode (16), an electron transporting layer (15), an emitting layer (14), a hole transporting layer (13) and an anode (12) laminated in sequence. The hole transporting layer (13) includes a substance represented by:n where R 1 ,R 2 ,R 3 ,R 4 ,R 5 ,R 6 each independently represent a hydrogen atom, an alkyl group of from 1 to 6 carbon atoms, a halogen group, a cyano group, a nitro group, or an aryl group of from 6 to 15 carbon atoms, a fused aromatic group, an alkoxy group, an alkylamine group, an aryloxy group, or an arylamine group. |
