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.

Abstract: A window member includes a window including a first flat part, a first pattern part disposed on a side of the first flat part and having a groove pattern, and a second flat part disposed on an opposite side of the first flat part, the first pattern part being disposed between the first flat part and the second flat part; and a first light-blocking member disposed on a surface of the first flat part and not overlapping the first pattern part or the second flat part in a plan view. The first light-blocking member includes a 1-1-th light-blocking member, a 1-2-th light-blocking member, and a 1-3-th light-blocking member facing the 1-1-th light-blocking member. The 1-1-th light-blocking member, the 1-2-th light-blocking member, and the 1-3-th light-blocking member define a first accommodation space. The 1-3-th light-blocking member is spaced apart from the 1-1-th light-blocking member to define a first open area.

Abstract: A display device includes a substrate including a first surface from which a pattern including an end portion is defined and a second surface which is parallel to the first surface. When an inner radius from a reference line positioned above the end portion and parallel with the first surface of the substrate to a surface of the pattern defining about 90 degrees is referred to as a first inner radius and an inner radius from the reference line to the surface of the pattern defining about 45 degrees is a second inner radius, a ratio of the second inner radius to the first inner radius is about 0.7 or more.
