Abstract: A glass substrate includes: a first major surface; a second major surface that is opposite to the first major surface; an end surface interposed between the first major surface and the second major surface; a first boundary surface that is interposed between the first major surface and the end surface and connected to the end surface; and a second boundary surface that is connected to the first major surface and the first boundary surface. The second boundary surface is a convex curved surface, and the second boundary surface has a radius of curvature R2 of 0.1 mm or larger and 2.0 mm or smaller.

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.
