Abstract: A transparent substrate with a light shielding region includes a transparent substrate, and a light shielding region on a peripheral portion of one main surface of the transparent substrate. The light shielding region includes a first light shielding region and a second light shielding region. The first light shielding region has a luminous transmittance of 0.1 to 40%, and an average transmittance at a wavelength of 800 to 1,000 nm of 65% or more. The second light shielding region has an optical density of 4 or more. The second light shielding region has a luminous reflectance of 0.1 to 1% and an average reflectance R1 at a wavelength of 600 to 700 nm being 1.5 times or more of an average reflectance R2 at a wavelength of 400 to 600 nm of the second light shielding region.

Abstract: A cover glass includes: a glass substrate having a convex and concave shape formed on at least one of surfaces thereof by an antiglare treatment; and an antireflection film disposed on the surface of the glass substrate, the surface having the convex and concave shape. In the cover glass, a difference Δa* in a* value between any two points within a surface of the cover glass on the side where the antireflection film is present and a difference Δb* in b* value between any two points within the surface of the cover glass on the side where the antireflection film is present satisfy the following expression: √{(Δa*)2+(Δb*)2}≤4.

Abstract: A glass laminate includes a glass substrate including a first main surface and a second main surface, and a functional layer at least on the first main surface. The functional layer includes at least two layers having a refractive index different from each other and the at least two layers are alternately laminated. The functional layer includes an outermost layer farthest from the glass substrate and a second layer that is adjacent to the outermost layer and lies closer to the glass substrate than the outermost layer. The outermost layer includes SiO2 as a main component. The second layer has a carbon concentration of 3×1018 atoms/cm3 or more and 5×1019 atoms/cm3 or less, and the carbon concentration of the second layer is lower than that of the outermost layer.

Abstract: A glass laminate includes a glass substrate including a first main surface and a second main surface, an antireflection layer on at least one of the first main surface and the second main surface, and an antifouling layer on the antireflection layer. The antireflection layer includes at least one low refractive index layer and at least one high refractive index layer, and the low refractive index layer and the high refractive index layer being alternately laminated. The antireflection layer includes an outermost layer farthest from the glass substrate and the outermost layer is the low refractive index layer including SiO2 as a main component. A distribution of fluorine concentration in a thickness direction of the outermost layer, measured by secondary ion mass spectrometry, has a peak.
