    Abstract: A glass article includes a first surface, a second surface opposed to the first surface, a first compressive region extending from the first surface to a first compression depth, a second compressive region extending from the second surface to a second compression depth and a tensile region between the first compression depth and the second compression depth. A stress profile of the first compressive region includes a first segment located between the first surface and a first transition point and a second segment located between the first transition point and the first compression depth. A depth from the first surface to the first transition point ranges from 6.1 μm to 8.1 μm. A compressive stress at the first transition point ranges from 207 MPa to 254 MPa. A stress-depth ratio of the first transition point ranges from 28 MPa/μm to 35 MPa/μm.

    Abstract: A glass article includes first and second surfaces opposed to each other; a first compressive region extending from the first surface to a point at a first compression depth; a second compressive region extending from the second surface to a point a second compression depth; and a tensile region disposed between the first and second compressive regions. A stress profile of the first compressive region includes a first segment between the first surface and a first transition point and a second segment between the first transition point and the first compression depth. A depth from the first surface to the first transition point is 8.1 μm to 9.5 μm, a stress at the first transition point is greater than or equal to 197 MPa, and a stress at a point of 50 μm in a depth direction from the first surface is greater than or equal to 75 MPa.
