Abstract
Abstract A method for manufacturing a color filter which comprises arranging colorants on a substrate by using inks capable of curing by the application of energy, said method comprising (1) a step of imparting, to the substrate, the inks capable of curing by the application of energy to form colored portions, (2) a step of applying the energy to the substrate to partially cure the colored portions, (3) a step of forming an energy-curable resin layer on the partially cured colored portions, and (4) a step of curing the partially cured colored portions and the resin layer by the application of the energy.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
80 words
A method for manufacturing a color filter which comprises forming a colored pattern on a substrate by imparting energy-curable inks of different colors, comprising the steps of: (1) imparting, to the substrate, the energy-curable inks to form a colored pattern, (2) applying the energy to the substrate to partially cure the inks applied to the substrate, (3) forming an energy-curable resin layer over the substrate, and (4) curing the inks and the resin layer by the application of the energy.
Claim 2
Independent Claim
80 words
A method for manufacturing a color filter which comprises forming a colored pattern on a substrate by imparting energy-curable inks of different colors, comprising the steps of: (1) imparting, to the substrate, the energy-curable inks to form a colored pattern, (2) applying the energy to the substrate to partially cure the inks applied to the substrate, (3) forming an energy-curable resin layer over the substrate, and (4) curing the inks and the resin layer by the application of the energy.
Claim 3
Dependent Claim
