NOVELTY - The method involves forming an organic compound layer into a primary film, and drying the primary film by a wet process. A coating-film surface of the organic compound layer is surface-treated by carrying out a plasma electro-discharge treatment, where surface free energy of the coating-film surface is 20-50 millijoules per meter square. Another organic compound layer is formed into a secondary film. The secondary film is dried on the former organic compound layer by the wet process. An organic solvent is used as a coating liquid solvent of the organic compound layers.    USE - Method for manufacturing an organic electronics device i.e. white-luminescence organic electro-luminescent (EL) element, that is utilized as an organic solar cell, organic transistor and a light-emitting light source of an electronic device. Uses include but are not limited to a backlight for domestic illumination and in-vehicle illumination, timepiece, signboard advertisement, signal apparatus, optical storage medium, electro-photographic copying machine, optical communication processor, photosensor, white-luminescence organic electro-luminescent (EL) display device, and full color LCD display e.g. active-matrix LCD display and passive-matrix LCD display.    ADVANTAGE - The method allows manufacture of the organic EL element without performing interlayer mixing of the organic compound layers in a coating process so as to improve performance of the organic EL element in an effective manner, thus facilitating mass production of the organic EL elements, and hence minimizing manufacturing time and cost.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an organic electronics device.
