Abstract
A color separation filter which is formed through use of dyestuffs provided with monomolecular film forming properties in which molecules can be absorbed by air-water interfaces and patterning properties capable of forming patterns through exposure by ionizing radiations. A method of manufacturing a color separation filter which comprises a step of forming monomolecular films of dyestuffs provided with monomolecular film forming properties and patterning properties, a step of piling a plurality of monomolecular films to form cumulative films and a step of patterning the cumulative films by radiating ionizing radiations to the cumulative films.
