Abstract: A base with a low-reflection film includes: a transparent base; a low-reflection film formed on a first principal surface of the transparent base; and a black printed part formed on a part of a second principal surface of the transparent base opposite to the first principal surface, in which a luminous reflectance R of the base with the low-reflection film with respect to incident light from the low-reflection film side is 2% or less in a region of the transparent base having the black printed part, and a ratio R1/R2 between a luminous reflectance R1 of a surface of the low-reflection film and a luminous reflectance R2 at an interface of the black printed part with the transparent base is ⅙ or more.

Abstract: The present invention relates to a cover member including a transparent base having first and second main surfaces, an antifouling layer formed on at least a part of the first main surface, a printed layer formed on at least a part of the second main surface, and an adhered member adhered on an antifouling layer-side surface, in which when an adhered-member-contact-portion projected region is defined as a prescribed region in the second main surface, the printed layer is provided on at least a part of a near-boundary region defined as a region from a boundary of the adhered-member-contact-portion projected region to an inward at 1,000 μm from the boundary, and no printed layer is provided on at least a part of an inner region defined as a region 500 μm or more inside from the boundary of the adhered-member-contact-portion projected region.

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 transparent substrate includes a first principal surface; a second principal surface as a principal surface on the opposite side of the first principal surface; a lateral surface extending between the first principal surface and the second principal surface; and a first boundary surface disposed between the first principal surface and the lateral surface and having a plurality of concave portions; wherein the first boundary surface is configured such that each of the concave portions has a bottom with a curvature and that the frequency of a maximum curvature is less than 3% in a frequency distribution of the curvatures of the concave portions.
