ABSTRACT:
A relatively large-sized square substrate for use in the production of a color filter for liquid crystal display, a color image sensor or the like is applied with a coating film of a viscous liquid such as a photosensitive resin. For producing the coating film, the substrate is placed with its surface extending horizontally and the viscous liquid is dropped on the surface in a line along an edge portion of the surface. Then, a squeezee rod is moved along the surface with a predetermined gap maintained between the squeezee rod and the surface, to spread the viscous liquid over at least a part of the surface, whereby a predetermined thickness of the spread viscous liquid is obtained. Thereafter, the substrate is spinned in the plane of the surface thereof to disperse the spread viscous liquid uniformly by centrifugal force over the entire surface of the substrate, whereby a thin coating of the liquid of a uniform thickness is formed on the surface of the substrate.
