Abstract

PURPOSE:To obtain colored filters of good spectral characteristics in high accuracy by selecting a hydrophilic polymer as a dyeing polymer layer and dry- etching it. CONSTITUTION:A solution consisting of hydrophilic polymer such as PVA or the like and dyes such as rhodamine or the like is applied on a substrate 11 to form a colored polymer layer 12. Then a photoresist layer 13 is applied and provided, and further is exposed and developed to form a etching mask 14. Dry etching is made at a nonmask part and a filter element 15 having a prescribed pattern is formed on the substrate 11. By repeating this step several times, a colored filter constituted of filter elements having plural colors, is obtained.
