Abstract:
A color filter fabricating method, comprising the steps of:placing a color filter forming substrate formed by providing a transparent conductive film and a transparent thin semiconductor film on a transparent substrate in this order so that at least the thin semiconductor film of the color filter forming substrate contacts an aqueous electrodeposition liquid which contains a colorant, a transparent, high-dielectric material having a particle diameter of 100 nm or less, and a polymeric material that has cross-linkable groups in molecules and decreases in solubility and dispersibility for an aqueous liquid, depending on a change in pH; in this state, irradiating a selected region of the thin semiconductor film with light to apply a voltage between the thin semiconductor film of the selected region and an opposing electrode; and depositing a high-dielectric colored film in the selected region of the thin semiconductor film.
