PURPOSE:To provide the color filter having a uniform film thickness by forming electrodes as second anodes on the same transparent substrate in at least the region on the outer periphery of the transparent electrode part to be finally used for display as the color filter. CONSTITUTION:Electrode patterns 2 for obtaining conduction with a power source, electrode patterns 3 to constitute color filter layers and patterns 6 as the second anode electrodes in the region on the outer periphery of the electrode patterns 3 are formed at the time of forming the film of the transparent electrode ITO on a glass substrate 1. Pigment films are thereafter formed on the electrodes 3. An electrolysis is effected by immersing the glass substrate 1 as anode and a stainless steel substrate as cathode in a prescribed aq. miscelle soln. in this formation. Silver paste is applied on the electrodes 2 and after all the electrode patterns 2, 3, 6 are integrally conducted, the patterns are connected to the power source and the substrates are immersed down to the liquid level at which the electrodes 3 and the electrodes 6 are completely immersed in the soln about the glass substrate 1. Consequently, the blue pigment films are formed on the ITO electrodes. |
