Patent number: 10209554Abstract: The present invention discloses a method for producing a laminated-resin black matrix that has a sufficient optical density and a low reflectance and that can be precisely processed, and a color filter substrate that includes a laminated-resin black matrix substrate produced by the method. The method for producing a laminated-resin black matrix substrate includes the step of exposing, in a single step, a laminate of a coating A of a non-photosensitive resin composition A that contains a light-shielding material and a coating B of a resin composition B that contains a light-shielding material, the laminate being on a substrate, and the step of developing the exposed laminate. The color filter substrate includes red, green, or blue pixels formed in apertures in a laminated-resin black matrix substrate produced by the method.Type: GrantFiled: June 12, 2014Date of Patent: February 19, 2019Assignee: Toray Industries, Inc.Inventors: Masahito Nishiyama, Yoshinori Matoba, Harushi Nonaka
