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.
