PROBLEM TO BE SOLVED: To obtain a high definition black matrix substrate by using current conditions for manufacturing a black matrix.SOLUTION: The following method for manufacturing a black matrix substrate 10 is used. The method comprises the steps of: applying a first black photosensitive resin composition 5a on a substrate 3; exposing the first black photosensitive resin composition 5a through a first photomask 11a; developing the first black photosensitive resin composition 5a; post-baking the first black photosensitive resin composition 5a to form a first black matrix 9a; applying a second black photosensitive resin composition 5b on the substrate 3 and the first black matrix 9a; exposing the second black photosensitive resin composition 5b through a second photomask 11b; developing the second black photosensitive resin composition 5b; and post-baking the second black photosensitive resin composition 5b to form a second black matrix 9b.
