Abstract: Provided is a black light-shielding member, which has an excellent effect of anti-reflection that based on low glossiness and has a high blackness. A black light-shielding member including a substrate film, a resin-made light-shielding layer having a concave-convex shape formed on at least one surface of the substrate film, and a blackened layer formed on the resin-made light-shielding layer is produced. By adjusting an arithmetic mean surface roughness Ra of the surface on which the light-shielding layer and the blackened layer are formed to be 0.25 μm or more, and the maximum thickness of the blackened layer is less than the said Ra, a blackness with an L value of 12 or less is achieved.
