Abstract: A window includes a base region and a compressive stress region disposed on the base region. The compressive stress region includes Li+, Na+, and K+ ions. The compressive stress region includes a first compressive stress portion in which a concentration of the K+ ions decreases, a concentration of Na+ ions increases, and a concentration of the Li+ ions increases, from a surface of the window toward the base region. A second compressive stress portion is adjacent to the first compressive stress portion. In the second compressive stress portion, the concentration of the Na+ ion decreases and the concentration of the Li+ ion increases, from the first compressive stress portion toward the base region. The window thereby has a high surface compressive stress value and impact resistance.

Abstract: A display device includes a display panel, a patterned glass disposed on the display panel, where the patterned glass includes a first non-patterned portion, a patterned portion, and a second non-patterned portion which sequentially are arranged in a first direction, a protective layer disposed on the patterned glass, and a first window adhesive layer disposed between the patterned glass and the protective layer. The protective layer has an elastic modulus in a predetermined range, a maximum value of an elastic modulus of the protective layer is constant, and a minimum value thereof varies in proportion to a thickness of the first window adhesive layer.

Abstract: A display device includes a display module folded with respect to a folding axis extending in a direction and a window disposed on the display module and including a folding portion and a non-folding portion, the folding portion being folded with respect to the folding axis. The folding portion includes a first folding surface adjacent to the display module and a second folding surface opposite to the first folding surface and spaced apart from the first folding surface. Multiple first grooves may be defined in the first folding surface, multiple second grooves may be defined in the second folding surface, and a ratio of a Young's modulus of the folding portion to a Young's modulus of the non-folding portion may be in a range of about 30/70000 to about 2000/70000.

Abstract: A display device includes a display panel, and a pattern glass disposed on the display panel and including a first non-pattern portion, a pattern portion, and a second non-pattern portion, which are arranged in a first direction. The pattern portion includes a plurality of patterns having a shape and arranged in the first direction and a second direction intersecting the first direction, and openings defined through the pattern glass between the plurality of patterns adjacent to each other. Each of the openings has a symmetrical shape with respect to a third direction intersecting a plane defined by the first and second directions based on a symmetry axis extending in the second direction. The symmetry axis passes through a midpoint of a thickness of the pattern glass.
