PCT No. PCT/JP93/01198 Sec. 371 Date Mar. 15, 1994 Sec. 102(e) Date Mar. 15, 1994 PCT Filed Aug. 26, 1993 PCT Pub. No. WO94/06157 PCT Pub. Date Mar. 17, 1994.A functional layer, such as a light emitting layer, of an organic electron device, such as an organic electroluminescence device, is provided. The function layer includes a small amount of a charge injection auxiliary material capable of enhancing charge injection properties. The charge injection auxiliary material comprises a stilbene, distyrylarylene or tris(styrylarylene) compound and is employed in an organic electron device wherein a positive-hole transporting organic functional layer is subjected to positive-hole injection from an external layer by incorporating the charge injection auxiliary material in the functional layer. The organic electroluminescence device provided by the present invention has a lowered applied voltage, an enhanced luminous efficiency and a prolonged service life.
