Abstract:
An object of the present invention is to provide an organic thin-film laminate capable of suppressing function reduction even when an intermediate layer is formed using a wet method. The organic thin-film laminate has one or more organic functional layers, the organic thin-film laminate being characterized by being provided with: a first light-emitting layer 12 containing a first light-emitting-layer material that is soluble in a polar solvent other than a fluorinated solvent, and is insoluble in a fluorinated solvent; a second light-emitting layer 14 laminated on the first light-emitting layer 12; and one or more intermediate layers comprising a non-curable material, the intermediate layers being provided between the first light-emitting layer 12 and the second light-emitting layer 14, an intermediate layer 13, among the one or more intermediate layers, containing a conductive polymer having no polymerizable group and containing a fluorinated solvent in the range of 1-1000 mass ppm.
