Patent ID: 7839470

Claim:
A method of manufacturing a color liquid crystal panel that has a transparent substrate, an insulation film that is on the transparent substrate and that has a convex-concave surface and a contact hole, and a reflective electrode on the insulation film, the method comprising the steps of: placing a first photomask over a raw material film of the insulation film, the first photomask having first openings corresponding to a closed area, the contact hole and a peripheral portion thereof existing within boundaries of the first openings; forming first exposed portions of the raw material film using the first photomask, the first exposed portions each having a thickness less than that of the raw material film and a size corresponding to the first openings; placing a second photomask over the raw material film, the second photomask having a second opening corresponding to the contact hole; forming a second exposed portion of the raw material film using the second photomask, the second exposed portion having a thickness equal to that of the raw material film and a size corresponding to the second opening; removing the first and second exposed portions; and baking the raw material film to form the insulation film with the contact hole.
