Abstract
The present invention provides a process for producing a multicolor display without a photolithographic process which requires registration. The process comprises forming a transparent electroconductive layer on a transparent substrate, forming a desired colored layer patterned thereon, and subjecting the transparent electroconductive layer exposed between the gap of the patterned colored layers to a metal electroplating (or electrolytic reduction) to form a light-shielding layer.
