Abstract: A foldable display device according to the present disclosure includes a display panel including a display area and a non-display area, a touch panel disposed on the display panel and including a bridge electrode, a plurality of insulating layers, a first touch electrode, and a second touch electrode. The device includes a plurality of crack stoppers disposed in the non-display area of the touch panel and configured by patterning the insulating layers and an adhesive layer. The adhesive layer fills a space between the plurality of crack stoppers from which the insulating layers are removed, and is disposed between the display panel and the touch panel. Accordingly, crack occurrence may be suppressed even if a folding/unfolding operation of the foldable display device is repeated. Thus, crack occurrence in the foldable display device may be improved and at the same time, folding characteristics may increase.

Abstract: A foldable display device includes a display panel configured to be folded around a folding axis. The display panel includes spacers disposed in a non-folding area and a folding area, and the spacers may have different sizes or densities. Dimensions of the spacers may be in a direction of the folding axis or intersect the direction of the folding axis. The display panel also includes pixels in an active area that overlap with the spacers, which may help reduce peeling, cracking, defects, or reduction in pixel brightness due to folding of the display device.
