Abstract:
1. A film pattern forming method for forming a film pattern on a predetermined region of a substrate that has a predetermined shape, comprising: rendering a surface of the substrate liquid-repellent; applying droplets of a liquid containing material for forming the film pattern on the liquid-repellent surface of the substrate thereby forming a margin band of the applied droplets and forming a margin band film by drying or hardening the margin band; increasing liquid affinity of the surface of the substrate and a surface of the margin band film to form a film with liquid affinity continuously over the surface of the substrate and the surface of the margin band; and applying droplets of the liquid containing the material for forming the film pattern in the predetermined region circumscribed by the margin band film and thereby filling the predetermined region for forming the film pattern in the predetermined region so that a thickness of the film pattern formed in the predetermined region is smaller than a thickness of the margin band film.
