PURPOSE:To produce the color filter with the adhesion of a dyestuff thin film improved without deteriorating the drivability of a liq. crystal by forming the dyestuff thin film on a conductive substrate and forming a polymer structure in the void in the thin film and on the thin film. CONSTITUTION:An aq. colloidal soln. of micellar dyestuff grains 1 consisting essentially of the dyestuff grains 1 insoluble or difficultly soluble in water, a surfactant capable of being oxidized at least by electrolysis and a supporting electrolyte and in which the dyestuff grain 1 is surrounded by the surfactant is prepared. The micelle is broken by electrolytic oxidation to deposit the dyestuff grain 1 on the surface of ITO 3 formed on a glass substrate 4, and a dyestuff thin film is formed. The polymer structure 2 is formed in the void in the thin film and on the surface by the electrochemical or coating method, and the thickness of the structure is controlled to about 1/2 times that of the thin film. Consequently, a color filter with the adhesion of a dyestuff thin film drastically improved without deteriorating the liq. crystal drivability is obtained. |
