ABSTRACT:
An electrode plate with a color filter having a good planarity and suitable for a liquid crystal device is provided by forming on a transparent substrate a porous electroconductive film colored in a prescribed pattern by impregnation with an organic colorant. After being further coated with an insulating film and an alignment film, the electrode plate with a color filter may be applied to another electrode plate with a spacer therebetween to form a cell, which is then filled with a liquid crystal to form a liquid crystal device.
