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 display device includes a display panel curved in a direction and a fixing frame having a predetermined curvature, where the fixing frame is configured to support and fix the curved display panel. The curved display panel includes curved first and second display substrates facing each other; and an elastic member on an edge portion of a rear surface of the curved first display substrate and elongated in the direction in which the display panel is curved. The curved first display substrate has a larger radius of curvature than that of the curved second display substrate.
