An organic compound film is formed over a first electrode. An organic mask film containing an organic compound which has low solubility to water or a chemical solution including water as a solvent is formed over the organic compound film. An inorganic mask layer is formed over the organic mask film. Shapes of the organic mask film and the organic compound film are processed with the use of the inorganic mask layer, whereby an organic mask layer and an organic compound layer are formed. At least parts of the inorganic mask layer and the organic mask layer are removed with the use of water or a liquid including water as a solvent.
