Substrate with light-shielding film, manufacturing method of the substrate, and display device having the substrate

A black-matrix substrate comprising:

• a substrate;
• and
• a light-shielding film over the substrate, the light-shielding film having a plurality of openings and including:
• a base film over the substrate;
• a metal film on a top surface of the base film, a thickness of the metal film being thinner than a thickness of the base film;
• and
• a low-reflection film located between the base film and the metal film and having an optical reflectance lower than that of the metal film, a thickness of the low-reflection film being thinner than a thickness of the base film,
• wherein the substrate, the base film, the low-reflection film, and the metal film are stacked in this order,
• the base film includes at least one of a resin and an inorganic compound,
• the resin is selected from an acrylic resin, an epoxy resin, a polysiloxane resin, a polyimide resin, and a polyamide resin, and
• the inorganic compound is selected from silicon-containing inorganic compounds.
