Abstract
Provided is a display substrate and a manufacturing method thereof a display panel and a display device. The display substrate comprises: a base substrate, and black matrixes, color filters and a blocking layer provided above the base substrate, the blocking layer being provided above the black matrixes and the color filters and being configured to block diffusion of particles generated by the color filters and/or the black matrixes. In the solutions of the display substrate and a manufacturing method thereof and a display device provided in the present application, the blocking layer is provided above the black matrixes and the color filters, and can block the particles generated by the color filters and/or the black matrixes, preventing the generated particles from diffusing to the opposite substrate facing the display substrate, generation of the progressive Zara can be prevented.
