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 transparent substrate with a light-shielding layer including: a transparent substrate having a first main surface and a second main surface; an infrared ray-transmitting layer that is on the first main surface and forms a visible light-transmitting region that is an opening in a top view from the first main surface side; and a light-shielding layer that is on the infrared ray-transmitting layer and forms an infrared ray-transmitting region that is an opening to expose the infrared ray-transmitting layer in the top view from the first main surface side.

Abstract: A glass substrate includes a first major surface, a second major surface, an end surface, a first boundary surface, a second boundary surface, and a bent portion in which the first major surface is bent so as to be concave and the second major surface is bent so as to be convex. The bent portion includes a portion in which a distance D1 from the end surface to the first major surface in a tangential direction, extending from the end surface toward the first major surface, of the glass substrate is longer than a distance D2 from the end surface to the second major surface in a tangential direction, extending from the end surface toward the second major surface, of the glass substrate. A difference between the distance D1 and the distance D2 is 50 μm or larger.

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, 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.

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.
