摘要： A display substrate having a black matrix with a curved surface, a method for manufacturing the same and a display device are provided. The display substrate includes a black matrix disposed between adjacent pixels, wherein a sidewall of the black matrix is a concave curved surface. During the formation of a color film, since the sidewall of the black matrix is formed as a concave curved surface, color film droplets in one sub-pixel may return into the sub-pixel along the curved surface while splashing to the sidewall of the black matrix, thereby the contamination to adjacent pixels caused by the droplets splashing may be avoided, and a yield of the substrate may be ensured.
