摘要： An organic EL multi-color emitting device including a substrate, and a first light-emitting element and a second light-emitting element arranged on the surface of the substrate; the first light-emitting element including, between an anode and a cathode, a first organic layer, a second organic layer and a third organic layer in this sequence in a direction perpendicular to the surface of the substrate; the second light-emitting element including, between an anode and a cathode, a second organic layer and a third organic layer in this sequence in a direction perpendicular to the surface of the substrate; the first organic layer including a first light-emitting dopant; the third organic layer including a second light-emitting dopant; the second organic layer including any of (A) a compound including an arylamine site, and a furan site or a thiophene site, (B) a compound including an arylamine site and a site comprising a nitrogen-containing six-membered ring structure, (C) a compound including a carbazole site; and a furan site or a thiophene site, and (D) a compound including a carbazole site and a site including a nitrogen-containing six-membered ring structure.
