Abstract

A display substrate includes a substrate and a color filter layer disposed on the substrate. The color filter layer includes a plurality of filter units arranged in an array and a plurality of light-shielding units. Every two adjacent filter units are provided with a light-shielding unit of the plurality of light-shielding units therebetween. The light-shielding unit includes a filter pattern of a first color and a filter pattern of a second color that are stacked in a thickness direction of the substrate, the filter pattern of the first color is closer to the substrate than the filter pattern of the second color.
