<p>PURPOSE:To prevent pattern slip, to dispense with the dyeing prevention treatment for color change, and to render film thickness and dyeing degree uniform by forming an insulating layer on conductive layers between the display parts on a base plate and electrode terminals, and electrodepositing colored layers on the conductive layers used as electrodes from a soln. contg. a polymer and a dispersed dye hardly or not soluble in water. CONSTITUTION:Plural conductive layers 7 arranged on a base plate, insulated from each other, an insulating film 13 is formed on the conductive layers 7 between their display parts and electrode terminals, and the base plate 6 is immersed in a soln. obtained by dispersing an electrodeposiable polymer and a dye hardly or not soluble in water till its meniscus level reaches the film 13. Colored layers 8 are selectively formed on the layers 7 by electrodeposition from said soln. Then, the colored layers are likewise electrodeposited by repeatedly selecting other dyes. Such a polymer can disperse org. dye molecules and it can be deposited together with the dyes. As a result, the uniform film thickness and the uniform dyed degree of the colored layers 8 can be obtained and a fast color filter can be obtained. Although a display pattern is very fine, pattern slip is prevented and it is not necessary to execute dyeing prevention treatment for color change.</p> |
