ABSTRACT:
An easier method is provided to manufacture a light emitting device that can display a full-color image using a polymeric organic compound. In the present invention, some of polymeric organic compounds are dissolved in a protic solvent while the others are dissolved in an aprotic solvent and the obtained solutions are applied to form organic compound films having laminate structures. A conductive film to serve as an etching stopper is formed on the organic compound films, so that portions of the organic compound films that do not overlap the conductive film are etched away. By using wet etching and dry etching in combination, different organic compound films each composed of a plurality of polymeric organic compounds can be formed in different light emitting elements on the same substrate.
