A mask plate, a method for fabricating the same, a display panel and a display device are disclosed. The mask plate includes a shielding plate having an opening; the opening is surrounded by side sections along a thickness direction of the shielding plate. The opening includes: a notch disposed at an intersecting region between at least some of the side sections and a surface of the shielding plate, wherein an area of the opening close to the surface of the shielding plate is larger than that of the opening away from the surface of the shielding plate. The notch increases an area of a marginal region of a film layer evaporated on a base substrate and increases a flatness of the marginal region, thereby decreasing the possibility of fracture of the metal film layer to be formed thereafter due to a high step and increasing a defect-free of the products.
