A film forming device includes: a first discharge unit for discharging a first liquid material, in which a film forming material is dissolved in a solvent or dispersed in a dispersion medium; a second discharge unit for discharging a second liquid material containing a liquid with the same component as the solvent or the dispersion medium; and a removal unit for removing the solvent or the dispersion medium from droplets of the first liquid material arranged on a substrate by the first discharge unit, while removing the liquid, arranged on the substrate by the second discharge unit, from droplets of the second liquid material; wherein a film is formed on the substrate, by arranging the droplets of the first liquid material on first parts on the substrate by the first discharge unit, while arranging the droplets of the second liquid material on second parts on the substrate, which are separated from the first parts, by the second discharge unit, thereafter by removing the solvent from the droplets of the first liquid material arranged on the first parts, using the removal unit for solvent removing.
