Abstract
A glass plate, containing: a first main surface and a second main surface opposite to each other, wherein an in-plane void region having a plurality of voids is arranged on the first main surface, a plurality of internal void rows each having one void or two or more voids are arranged from the in-plane void region toward the second main surface, and a cut surface obtained by cutting the glass plate to pass through the in-plane void region and the plurality of internal void rows has a compressive stress layer formed by applying a chemical strengthening treatment in the center of the cut surface.
