Patent ID: 8315002

Claim:
A method for producing a color filter comprising the steps of: preparing a light shielding part forming composition containing at least a light shielding material and a resin; forming a light shielding part on a transparent substrate by using the light shielding part forming composition; and forming a colored layer in an opening part of the light shielding part, wherein the step of forming a light shielding part further comprises a process of coating the light shielding part forming composition onto the transparent substrate, using a half tone mask to change an exposing amount to the light shielding part forming composition and forming a shape of the light shielding part as follows: a width of a thick film region, 85% or more of a maximum film thickness of the light shielding part and disposed in a central part of the light shielding part, is in a range of 30% to 60% of a light shielding part linear width; and a width of each of thin film regions, 50% or less of the maximum film thickness of the light shielding part and disposed on both side parts of the light shielding part, is in a range of 10% to 20% of the light shielding part linear width.
