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 layercontaining 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 layerlaminated on the first light-emitting layer; and one or more intermediate layers comprising a non-curable material, the intermediate layers being provided between the first light-emitting layerand the second light-emitting layer, an intermediate layer, 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.

Organic thin-film laminate and organic electroluminescence element

To provide an organic electroluminescent element that can attain efficiency improvement by forming an electron injection layer by a film that is stable and excellent in uniformity, and forming a charge generation layer capable of effectively exhibiting the function. In an organic electroluminescent element provided with at least one organic layer between a pair of electrodes, an electron injection layer comprising a ZnO-containing layer, and a charge generation layer containing an electron acceptor-containing film in contact with the cathode side thereof and an electron donor-containing film adjacent thereto are formed.

Organic electroluminescent element

In a coating-type electron injection layer or electron transport layer using a metal oxide, the present invention aims at improving uniformity or stability of composition distribution and adhesion with another adjoining constituent layer, and improving film forming property, to thereby provide an organic electronic device and manufacture of the device whose efficiency is improved. In the organic electronic device having one pair of electrodes on a substrate, and having at least one organic layer between the electrodes, the electron injection layer or the electron transport layer is formed by application of a liquid material in which an alkaline metal salt and zinc-oxide nano particles are dissolved in alcohol.
