GLASS SUBSTRATE

The present invention provides a glass substrate in which the emission of light at a chamfered part in a curved part is suppressed. The glass substrate of the present invention is provided with a first main surface, a second main surface which is a main surface located on the side opposite to the first main surface, an edge face which is located between the first main surface and the second main surface, a first boundary face which is connected to the first main surface and the edge face, a second boundary face which is connected to the second main surface and the edge face, and a curved part in which the first main surface is curved in a concaved shape and the second main surface is curved in a convexed shape, wherein the curved part includes a part in which a distance D1, which is a distance from the edge face to the first main surface as determined in the tangential direction from the edge face toward the first main surface in the glass substrate, is longer than a distance D2, which is a distance from the edge face to the second main surface as determined in the tangential direction from the edge face toward the second main surface in the glass substrate, and the difference between the distance D1 and the distance D2 is 50 µm or more.
