Abstract: A display substrate, a method for manufacturing the same and a display device are provided. The display substrate includes a black matrix disposed between adjacent pixels, and a sidewall of the black matrix is a concave curved surface. Since the sidewall of the black matrix is formed as a concave curved surface, when color film droplets in one sub-pixel splash to the sidewall of the black matrix in forming of a color film, the droplets can return into the sub-pixel along the curved surface, thereby avoiding contamination to adjacent pixels by the droplets splashing, and ensuring substrate yield.
