<p>PURPOSE:To easily and efficiently form light shielding parts with high accuracy by subjecting a photosensitive resin to full-surface exposing from the rear side of a base material then to exposing through pattern masks from the surface coated with the photosensitive compsn. CONSTITUTION:The negative type photosensitive resin compsn. which contains a material having the property to shield visible light, for example, a black coloring material, and is cured in exposed pars is applied on the base material by means, such as spin coater or roll coater. The photosensitive resin compsn. contg. the material having the property to shield visible light is then applied between picture elements and is subjected to the full-surface exposing from the rear surface. In addition, the photosensitive resin compsn. contg. the material having the property to shield visible light is exposed from its front surface through the chromium mask having the patterns disposed to expose only the parts between the picture elements and is thereby cured. The visible light shielding layer without having the spacing from the picture elements and having the thickness equal to the thickness of the picture elements is formed by simultaneously or successively executing the full-surface exposing from the rear surface and the mask exposing from the front surface. The unexposed photosensitive resin compsn. existing on the picture elements is removed by washing with a proper solvent.</p> |
