  • Patent number: 9978995
    Abstract: 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.
