Abstract: A transparent substrate with a light-shielding layer, including: a transparent substrate including a first main surface and a second main surface; an infrared ray-transmitting layer that is disposed so as to be in contact with the first main surface of the transparent substrate, transmits an infrared ray, and shields a visible light; and a light-shielding layer that is disposed on the infrared ray-transmitting layer, includes an opening that exposes a part of the infrared ray-transmitting layer, and shields the visible light and the infrared ray, in which the light-shielding layer includes an end portion that projects from an end portion of the infrared ray-transmitting layer, that is closest to an outer circumference of the transparent substrate, and is in contact with an end face of the infrared ray-transmitting layer and the transparent substrate.

Abstract: The present invention relates to a film-attached glass substrate, characterized by: being provided with a glass substrate having two primary surfaces each having a compressive stress layer, and a film containing 1 at % or more of K disposed on one of the primary surfaces of the glass substrate; and the ratio of the difference in the amount of K in the compressive stress layer between the primary surfaces, the ratio being represented by formula (1), being −0.027 to 0.027. Formula (1): Ratio of difference in amount of K of compressive stress layer between primary surfaces=(amount of K in first primary surface−amount of K in second primary surface)/[(amount of K in first primary surface+amount of K in second primary surface)/2]

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 chemically strengthened glass including a first main surface having an area of 12,000 mm2 or larger and a second main surface, and an anti-fingerprint treated layer provided on or above the first main surface. The chemically strengthened glass has a depth of compressive stress layer DOL of 20 μm or larger, has a tensile stress layer having a P2O5 content of 2 mol % or less, and has A×B of 135 or larger, provided that, among oxide components constituting the tensile stress layer, a total concentration of Li2, Na2O, and K2O is A mol % and a concentration of Al2O3 is B mol %. The anti-fingerprint treated layer includes a surface having a frictional electrification amount, as determined by Method D described in JIS L1094:2014, of 0 kV or less and −1.5 kV or more.
