    Abstract: A glass substrate has a first surface, a second surface opposite to the first surface, and a thickness from the first surface to the second surface. The glass substrate includes a first region, a second region, and a third region. The first region extends from the first surface a first depth into the glass substrate and has a first compressive stress. The second region extends from the second surface a second depth into the glass substrate and has a second compressive stress different from the first compressive stress. The third region is between the first region and the second region. In the glass substrate, the first compressive stress has a maximum value at a location between the first surface and the first depth, and the second compressive stress has a maximum value at a location between the second surface and the second depth.

    Abstract: Provided is a window molding apparatus including an inner molding part including a core molding part, which includes a plurality of sub-bottom surfaces having different curvature radii, and a flat molding part spaced apart from the sub-bottom surfaces and disposed on the core molding part, and an outer molding part which is disposed below the inner molding part with a member to be processed therebetween and in which a groove corresponding to the core molding part is defined. The outer molding part includes a lower surface, an upper surface configured to face the lower surface, and a plurality of sub-groove surfaces having different curvature radii that define the groove to provide a window including sub-bent portions having different curvature radii.

    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.

    Abstract: A glass polishing apparatus includes a jig that holds a glass structure. The glass polishing apparatus includes a first flat portion, a second flat portion opposite to the first flat portion, and a curved portion connecting the first flat portion to the second flat potion The jig and includes a first holding surface holding the first flat portion, a second holding surface disposed opposite to the first holding surface and holding the second flat portion, and a third holding surface connecting the first holding surface to the second holding surface and holding the curved portion. At least a portion of a roller unit having a cylindrical shape is inserted between the first flat portion and the second flat portion.
