Color filter and method for manufacturing the same

Abstract

A method for manufacturing a color filter having a high resolution and excellent controllability, in few steps without using a photolithographic process is disclosed. The method includes: preparing a substrate produced by sequentially forming a transparent electroconductive film and a semiconductor film on a transparent substrate; preparing a water-based liquid in a vessel, the water based liquid containing a coloring material and an electrodeposition material which is chemically dissolved or precipitated/sedimented by changes in the pH; securing the substrate having the transparent electroconductive film, to which means for supplying a current or an electric field according to an image pattern is connected, such that the semiconductor thin film is dipped in the water-based liquid; disposing a counter electrode in the vessel and disposing a mask pattern on the transparent substrate and applying light to selectively precipitate an electrodeposition film, which includes electrodeposition materials, on a portion at which electromotive force was generated with light irradiation, thereby forming a monochromatic color filter. A plurality of coloring materials, which each have a different hue, can be used and the steps for forming a monochromatic color filter can be repeated for each material having a different hue to form a polychromatic color filter.
