ABSTRACT:
An organic EL element comprising; an anode, a cathode, and an organic layer sandwiched therebetween containing at least an emitting layer, wherein a ratio, [In3d5/2]h/[In3d5/2]n, is from 0.9 to 1.2 wherein [In3d5/2]his the half band width of a spectral peak derived from a 3d5/2orbit of an In atom in the surface of the anode, and [In3d5/2]nis the half band width of a spectral peak derived from a 3d5/2orbit of an In atom in the interior of the anode, the spectral peaks being measured by X-ray photoelectron spectroscopy (XPS): and the method for the production thereof.
