Abstract
A method for manufacturing a color filter which includes arranging an electroconductor and a transparent substrate carrying an electroconductive transparent thin layer in an electrodeposition bath so that the electroconductor and the substrate are disposed in spaced and parallel relationship and that a baffle is disposed between the thus arranged electroconductor and the substrate, and carrying out electrodeposition in the electrodeposition bath by using the electroconductive transparent thin layer as one electrode and the electroconductor as a counter electrode permits the production of a desired color filter having superior layer flatness, even when the substrate enlarged in the size is used.
