Abstract
A color film substrate, a method for manufacturing the same, and a display device are provided, and relate to the field of display technology. The method includes providing a basal substrate, a surface of the basal substrate including a plurality of separated color filter regions and a plurality of interval regions, each interval region being located between two adjacent color filter regions, forming a color filter pattern in each color filter region, and forming a transparent filling pattern in each interval region, and performing a blackening process to the filling pattern so that the filling pattern is converted into an opaque pattern.
