Claim:
1. A display substrate, comprising: a base substrate, and a color film structure and a transparent conductive oxide film layer subsequently laminated on the base substrate, wherein the color film structure comprises a plurality of color filter units arranged in a matrix and having different color; wherein at least one color of the color filter units in the color film structure comprises at least two layers of laminated color filter films, refractive indices of the color filter films gradually increases in a direction from the base substrate towards the transparent conductive oxide film layer, and one layer of the color filter films adjacent to the base substrate has a refractive index larger than that of the base substrate, one layer of the color filter films adjacent to the transparent conductive oxide film layer has a refractive index less than that of the transparent conductive oxide film layer.
