Method for manufacturing a substrate having window-shaped and frame-shaped coating films on the surface thereof.

摘要

A method for manufacturing a substrate useful as a color filter for LCD and having window-shaped coating films and a frame-shaped, functional coating film at the regions not occupied with the window-shaped coating films, which comprises the steps of: (a) forming a functional coating film on a transparent substrate having electrically conductive circuits on a surface thereof, (b) superposing a photomask having a predetermined pattern on the surface of the coating film formed in step (a), and exposing the thus masked coating film to light, (c) subjecting the intermediate product to developing to leave a frame-shaped coating film, and (d) subjecting the resulting substrate formed through steps (a) to (c) to electro-deposition to form electro-deposition coating films on the electrically conductive circuits, enables production of coating films of fine pattern with improved precision.
