Abstract:
A glass product includes: a first compressive region at a first surface; a second compressive region at a second surface; and a tensile region between the first and second compression regions. A stress profile of the first compressive region includes a first trend line between the first surface and a first transition point, a second trend line between the first transition point and a second transition point, and a third trend line between the second transition point and a point at a first compression depth from the first surface. A depth from the first surface to the first transition point is 10 μm or less, a stress at the first transition point is 200 MPa or greater, a depth from the first surface to the second transition point is 50 μm to 80 μm, and a stress at the second transition point is 40 MPa to 100 MPa.
