Abstract: A 3D cover glass, having a polygonal shape in a plan view which corner part may comprise a rounded portion, and containing a central part being flat plane, and curved parts each with a three-dimensional curved surface having a curvature radius of 100 mm or less on peripheries of at least two of the sides of the polygonal shape, wherein the 3D cover glass shows the maximum value of retardation per 1 mm thickness being 16 nm/mm or less when measured by irradiating a light having a wavelength of 543 nm onto the central part orthogonally.
