Abstract: A flexible display device, which has a bending area and a non-bending area, includes a display panel, and a window member disposed on the display panel and including a first glass substrate, a second glass substrate disposed opposite to the second glass substrate, and a bonding layer disposed between the first glass substrate and the second glass substrate. The bonding layer includes a first bonding part overlapping the bending area and a second bonding part overlapping the non-bending area and having a modulus greater than a modulus of the first bonding part.

Abstract: A method of manufacturing a strengthened glass substrate, the method including: thermoforming a glass substrate, wherein a surface of the glass substrate includes defective depressions generated by the thermoforming; forming a silica rich layer by adding an acid to the surface of the glass substrate including the defective depressions generated by the thermoforming; removing the silica rich layer and a portion of the defective depressions by cleaning the surface of the glass substrate on which the silica rich layer is formed with an alkali; and eliminating the remaining portion of the defective depressions by polishing the surface of the glass substrate including the remaining portion of the defective depressions.

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.
