摘要：
Disclosed are an external light shielding film with a substrate including a transparent resin, an external light shielding pattern formed on a surface of the substrate and having a plurality of external light shielding parts including a light absorbing material, a method of manufacturing the external light shielding film, and a filter for a display having the external light shielding film. The light absorbing material consists of a base resin and a light absorbing substance, and at least one of a concentration of the light absorbing substance and a refractive index of the base resin varies in a stepwise manner.
