Cover material and display device

To suppress reduction in rigidity. A cover material has a curvature in a first direction X and a curvature in a second direction Y. The curvature in the first direction X and the curvature in the second direction Y intersect with each other on a plane of the cover material . The radius of curvature of the curvature in the first direction X is 60 mm or more and 300 mm or less. The radius of curvature of the curvature in the second direction Y is 1000 mm or more and 14000 mm or less.
