    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 a first surface and a second surface opposite to the first surface in a thickness direction. A thickness from the first surface to the second surface ranges from about 20 micrometers (μm) to about 100 μm. A first brittleness index defined by following Equation 1 is about 1.5*10−4 μm0.5 or more: First ⁢ brittleness ⁢ index ⁢ = 1 / B = K IC / H v ( μ ⁢ m 0.5 ) [ Equation ⁢ 1 ] where ‘B’ is brittleness, ‘KIC’ is fracture toughness, and ‘Hv’ is hardness, and a stretch index defined by following Equation (2) is about 0.95 or more: β KWW = 1 - ( T 0 - T g ) 2 D [ Equation ⁢ ( 2 ) ] where ‘D’ is a strength factor (=BVFT/T0), ‘T0’ is a Vogel temperature, and ‘Tg’ is a glass transition temperature.
