    Abstract: A transparent substrate having an antiglare function includes first and second faces. The transparent substrate has a resolution index value T, a reflected image diffusivity index value R, and a sparkle index value S satisfying T≥0.25, R≥0.8, and 0.75≤S≤0.95, respectively. The resolution index value T is calculated as (luminance of zero-degrees transmission light)/(luminance of total transmission light). The reflected image diffusivity index value R is calculated as (R2+R3)/(2×R1), where R1 denotes a luminance of reflected light reflected at first angle α1, and R2, R3 denote luminance of reflected light at the second angle α2, the third angle α3, respectively, with respect to the first angle α1. The sparkle index value S is calculated as 1−(Sa/Ss), where the first sparkle Sa and the second sparkle Ss denote a sparkle value of the transparent substrate and a sparkle value of a glass substrate, respectively.

    Abstract: A chemically strengthened glass includes a compressive stress layer. A compressive stress is 200 MPa or more at a surface of the chemically strengthened glass. A depth in the compressive stress layer at which the compressive stress is 50 MPa from the surface is 50 μm or more. A depth in the compressive stress layer at which the compressive stress is 30 MPa from the surface is 60 μm or more. A critical stress intensity factor KIC is 0.75 MPa·m1/2 or more.

    Abstract: The present invention relates to a glass plate including a first main surface subjected to antiglare treatment, and a second main surface opposed to the first main surface, in which a clarity index value T, a reflection image diffusiveness index value R and an anti-sparkle index value S satisfy respective relations of: clarity index value T≥0.8; reflection image diffusiveness index value R≥0.01; and anti-sparkle index value S≥0.85; and a transmission haze measured by a method according to JIS K 7136 (2000) being 15% or less. The glass plate of the present invention is excellent in clarity, reflection image diffusiveness and anti-sparkle, and also excellent in reproducibility of color.

    Abstract: A transparent substrate having an antiglare function includes first and second faces. The transparent substrate has a resolution index value T, a reflected image diffusivity index value R, and a sparkle index value S satisfying T≥0.25, R≥0.8, and 0.75≤S≤0.95, respectively. The resolution index value T is calculated as (luminance of zero-degrees transmission light)/(luminance of total transmission light). The reflected image diffusivity index value R is calculated as (R2+R3)/(2×R1), where R1 denotes a luminance of reflected light reflected at first angle α1, and R2, R3 denote luminance of reflected light at the second angle α2, the third angle α3, respectively, with respect to the first angle α1. The sparkle index value S is calculated as 1−(Sa/Ss), where the first sparkle Sa and the second sparkle Ss denote a sparkle value of the transparent substrate and a sparkle value of a glass substrate, respectively.
