  • Patent number: 6056863
    Abstract: A method for manufacturing color filters, in which color layers for transmitting light within a specific wavelength range are formed on light-transmissive electrodes formed on a light-transmissive substrate. The light-transmissive electrodes are brought into contact with a deposition solution having an electrolytic solution and a pigment material dispersed therein. A voltage is applied through the contacting portions between the light-transmissive electrodes and the deposition solution. The deposition solution is then electrolyzed between the light-transmissive electrodes and a submerged electrode. Color layers are formed on the light-transmissive electrodes. Examples of possible methods to bring the light-transmissive electrodes into contact with the deposition solution include immersing the light-transmissive electrodes in the deposition solution, engaging the light-transmissive electrodes into contact with the surface of the deposition solution, and other methods.
