Abstract:
1. A method for producing an organic electroluminescent device, in which at least two layers containing an organic matter are stacked between a pair of electrodes, at least one of which is indium-tin oxide (ITO), the method comprising: coating a coating solution A directly on one electrode of the ITO so as to produce a first layer, wherein the coating solution A includes: an organic solvent; an organic matter having one selected from a hole injection material, a hole transport material, a hole injection/transport material, an electron injection materials, an electron transport materials, and an electron injection/transport materials; and an inorganic matter having at least one selected from Sn, In, tin oxide, indium oxide, and ITO, and coating directly on the first layer a solution B that includes a luminescent material and an organic solvent, so as to produce a second layer.
