Abstract

A glass plate (1), comprising a first compressive stress area (31) and a first tensile stress area (32) that are sequentially adjacent to each other from the edge to the inside, wherein the width of the first compressive stress area (31) is K1, and the width of the first tensile stress area (32) is K2; at least one surface of the glass plate (1) is provided with a conductive element (2), the orthographic projection of the conductive element (2) on the surface of the glass plate (1) does not overlap the first tensile stress area (32), the distance T between the side of the conductive element (2) close to the edge of the glass plate (1) and the edge of the glass plate (1) is greater than or equal to K1+K2, and the tensile stress in an orthographic projection area of the conductive element (2) on the surface of the glass plate (1) is less than or equal to 9 MPa. By controlling the position of the conductive element on the glass plate, in the forming process of the glass plate, the stress area formed by the contact between a mold and the glass plate overlaps or offsets the stress area formed by the conductive element, so that new stress distribution is formed at the edge of the glass plate, reducing the risk of glass plate breakage.
