Zusammenfassung:PURPOSE: Provided is an organic electroluminescence device, which uses a novel host material to give stable light-emitting characteristics. CONSTITUTION: The organic electroluminescence device comprises an electron injection electrode(cathode), a hole injection electrode(anode) and a light-emitting layer between both electrodes. In the organic electroluminescence device, the host material for the light-emitting layer is represented by the formula of B1-X-B2, wherein X represents a fused aromatic ring having 10-20 of carbon atoms, and each of B1 and B2 is selected from the group consisting of aryl, alkylaryl, alkoxyaryl, arylaminoaryl and alkylaminoaryl groups.
