    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 glass article includes lithium aluminosilicate, 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 disposed between the first compression depth and the second compression depth, where a stress profile of the first compressive region has a first local minimum point at which the stress profile is convex downward and a first local maximum point at which the stress profile is convex upward, where a depth of the first local maximum point is greater than a depth of the first local minimum point, and where a stress of the first local maximum point is greater than a compressive stress of the first local minimum point.

    Abstract: A display panel may include a first display substrate, a second display substrate disposed over the first display substrate, and a sealing member bonding the first display substrate and the second display substrate. The sealing member may include a frit sealing member including an outer region and an inner region, with the inner region disposed next to an inner side of the outer region and having a first crystallization temperature lower than a second crystallization temperature of the outer region, and an organic sealing member disposed next to an inner side of the frit sealing member.

    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 portion. 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.
