Abstract
The present invention is a color filter substrate comprising: a non-laminated part in which a colored layer and/or a transparent layer are arranged in a plane; and a laminated part in which parts of the colored layer and/or the transparent layer are laminated as two or more layers on a substrate, (1) a film thickness of a layer constituting the laminated part is not less than 90% and not more than 110% to a film thickness of a corresponding layer of the non-laminated part and/or (2) the colored layer and/or the transparent layer are formed using a dry film having a solid-phase resist layer having penetration amount in a penetration hardness test at 120° C. of not more than 0.5 μm.
