Abstract: A method for manufacturing a window includes providing a base glass, and strengthening the base glass by exposing the base glass to a strengthening molten salt and an additive. The additive contains at least one of Al2(SO4)3, Al(NO3)3, K2SiO3, Na2SiO3, KCl, Ca(NO3)2, and Mg(NO3)2, and a window having good surface compressive stress and excellent surface chemical resistance may thus Ire provided.

Abstract: An electronic device includes a display module that includes a foldable display portion and a non-foldable display portion, and a window disposed above the display module and that includes a foldable portion that corresponds to the foldable display portion and a non-foldable portion that corresponds to the non-foldable display portion. The window includes a first glass substrate, a second glass substrate that faces the first glass substrate, a protection layer that corresponds to the non-foldable portion and that is disposed between the first glass substrate and the second glass substrate and that includes an inorganic oxide, and a photoresist layer disposed between the protection layer and the first glass substrate. The first glass substrate includes a recessed portion that corresponds to the foldable portion formed on one surface adjacent to the protection layer.

Abstract: A window includes a first glass substrate, a second glass substrate facing the first glass substrate, and a bonding layer disposed between the first glass substrate and the second glass substrate. The window includes a first non-folding portion, a second non-folding portion, and a folding portion, the folding portion is disposed between the first non-folding portion and the second non-folding portion, and at least one of the first glass substrate and the second glass substrate includes a concave portion corresponding to the folding portion and defined on a surface adjacent to the bonding layer.
