Abstract: A window includes a tempered glass substrate that includes a base layer and a compressive stress layer including a first region and a second region. The second region includes a first portion that includes a first point and is adjacent to the first region, a second portion that includes a second point and is adjacent to the base layer, and a third portion that includes a third point and that is disposed between the first portion and the second portion. A compressive stress at the first point is in a range of about 100 MPa to about 250 MPa, a compressive stress at the second point is in a range of about 50 MPa to about 150 MPa, and a compressive stress at the third point is in a range of about 70 MPa to about 200 MPa.

Abstract: A method of manufacturing a window, includes: preparing a first preliminary glass substrate that does not contain Li+ ions and contains Na+ ions; providing a first strengthening molten salt to the first preliminary glass substrate to form a second preliminary glass substrate; providing heat to the second preliminary glass substrate at a temperature of about 400 to 500° C. for a period of about 3 to 7 hours to form a third preliminary glass substrate; and providing a second strengthening molten salt to the third preliminary glass substrate to form a window.
