Patent ID: 8796674

Claim:
A manufacturing method of an organic electronic device having a pair of electrodes on a substrate, and at least an organic functional layer and an organic charge transport layer between the electrodes wherein the organic charge transport layer comprises a first organic layer and a second organic layer, which comprises a process for forming a first organic layer by coating, on the organic functional layer, a first organic layer coating-liquid containing a charge transportable organic compound; and a process for forming a second organic layer by coating, on the first organic layer, a second organic layer coating-liquid containing the charge transportable organic compound and a metallic compound, in this order, wherein 80% by mass or more of the charge transportable organic compound in each of the first organic layer and the second organic layer, respectively, is the same compound, content of the metallic compound contained in the second organic coating-liquid is 20 to 40% by mass based on sum of content of the charge transportable organic compound and content of the metallic compound contained in the second organic layer coating-liquid, and, the process for forming a second organic layer by coating the second organic layer coating-liquid is conducted at a temperature of 5 to 15° C. higher than melting point of a solvent used in the second organic layer coating-liquid.
