Abstract:
1. A method of manufacturing a color liquid crystal panel, wherein the color liquid crystal panel comprises: a transparent substrate; an insulation film formed on the transparent substrate to have a convex-concave surface and a contact hole; and a reflective electrode formed on the insulation film, the method comprising the steps of: using a photomask of a lamination structure comprising a semi-transparent film and a light incidence preventing film, wherein the semi-transparent film has an opening corresponding to the contact hole and the light incidence preventing film has an opening corresponding to a recess portion of the insulation film and an opening corresponding to the contact hole and an periphery thereof, exposing a raw material film of the insulation film, forming an exposed portion whose thickness is equal to that of the raw material film of the insulation film by means of exposure to light transmitted through the openings formed on the light incidence preventing film and the opening formed on the semi-transparent film, and forming an exposed portion whose thickness is smaller than that of the raw material film of the insulation film by means of exposure to light transmitted through the openings formed on the light incidence preventing film and the semi-transparent film; and removing the exposed portions formed on the raw material film of the insulation film, baking the raw material film of the insulation film, and thereby forming the contact hole on the recess portion of the insulation film and the convex-concave surface on the insulation film.
