The filter consists of a substrate (10) with a coloured filter layer (12) formed upon. The filter layer (12) comprises, for example, three groups of filter picture elements (14R, 14G, 14B) having spectral characteristics respectively corresponding to red, green and blue. Each group filter picture elements is made of polyimide resin and dye. Further, each group of the filter picture elements (R, G, B) are arranged in direct contact with one surface of the substrate (10) without using any intermediate protecting film. The first group elements patterned on one surface of the substrate (10) are subjected to heat treatment at a high temp. of about 250 deg.C for example, to increase their resistance against the solvent. Then, a second coating layer for paterning the second group of filter elements is directly formed without using any intermediate protecting film. |
