Abstract
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 10. 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.
Claims8
A cover material, comprising:
- a transparent cover material that has a curvature in a first direction and a curvature in a second direction, having a thickness of 0.8 mm or more and 2.0 mm or less, wherein
- the curvature in the first direction and the curvature in the second direction intersect with each other on a plane of the cover material,
- a radius of curvature of the curvature in the first direction is 60 mm or more and 300 mm or less, and
- a radius of curvature of the curvature in the second direction is 1500 1600 mm or more and 8000 mm or less, wherein:
- the radius of curvature of the curvature in the first direction is smaller than the radius of curvature of the curvature in the second direction, and
- with respect to the radius of curvature of the curvature in the second direction, the radius of curvature of the curvature in the first direction is 0.00214 or more and 0.075 or less.
