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.

Abstract: A bonding device includes: a stage and a pressing part, which is placed on the stage and is movable toward the stage. A first layer, which is disposed on an upper surface of the stage, includes a first flat portion and first bending portions. A second layer, which is disposed below a lower surface of the pressing part, includes a second flat portion and second bending portions. The first and second bending portions may be disposed between the stage and the pressing part, in a state bent with curvatures, respectively. The curvature of a lower surface of each of the second bending portions is smaller than the curvature of an upper surface of each of the first bending portions.

Abstract: Disclosed is a display device including a display module that has at least one folding area, a first film disposed on the display module and having a first modulus, a second film disposed on the first film, being farther from the display module than the first film, and having a second modulus less than the first modulus, and a third film disposed on the second film, being farther from the display module than the second film, and having a third modulus less than the second modulus. The third modulus is equal to or less than about one-sixth of the first modulus.
