Crystallized glass of three-dimensional shape, chemically strengthened glass of three-dimensional shape, and method for producing crystallized glass of three-dimensional shape and chemically strengthened glass of three-dimensional shape

A three-dimensionally shaped crystallized glass, comprising:

• a petalite crystal and a lithium disilicate crystal,
• wherein the three-dimensionally shaped crystallized glass has an average transmittance of a light at a wavelength of 380 nm to 780 nm of 80% or more in terms of a thickness of 0.8 mm, the three-dimensionally shaped crystallized glass has a Young's modulus of 90 GPa or more, and the three-dimensionally shaped crystallized glass is formed by at least a bending-forming process at a bending temperature of from 700° C. to 900° C. so that a decrease of light transmittance by the bending-forming process is 3% or less.
