Patent ID: 7270586

Claim:
A method for producing an organic EL element comprising an anode, a cathode, an organic layer therebetween containing at least an emitting layer, and a surface protection film comprising an inorganic compound between the anode and the emitting layer, comprising the steps of: forming an anode on a substrate, giving an inorganic compound to the surface of the anode to form a surface protection film, forming an organic layer containing at least an emitting layer, and forming an cathode, wherein a ratio, [In3d 5/2 ] h /[In3d 5/2 ] n , is from 0.9 to 1.2 wherein [In3d 5/2 ] h is the half band width of a spectral peak derived from a 3d 5/2 orbit of an In atom in the surface of the anode, and [In3d 5/2 ] n is the half band width of a spectral peak derived from a 3d 5/2 orbit of an In atom in the interior of the anode, the spectral peaks being measured by X-ray photoelectron spectroscopy (XPS).
