An organic EL device has a hole injecting electrode 2,nan electron injecting electrode 6, an organic layernparticipating in a light emitting function disposed betweennthe electrodes. The organic layer includes a light emittingnlayer 4 comprising a conjugated polymer. The device furthernincludes an inorganic insulative hole injecting layer 3 or anninorganic insulative electron injecting layer 5. The devicencan take advantage of both organic and inorganic materials,nand has an improved efficiency, an extended effective life,nand a low cost. |
