Abstract: A foldable display device includes a display panel including a folding area and non-folding areas on both sides of the folding area in a folding direction; a first support substrate configured to support the display panel under the display panel and including a plurality of opening patterns corresponding to the folding area; and a second support substrate between the display panel and the first support substrate and including a plurality of protrusion patterns protruding to be inserted into the plurality of opening patterns. Sizes of the plurality of protrusion patterns are smaller than sizes of the corresponding plurality of opening patterns. Therefore, it is possible to improve durability and prevent or at least reduce degradation of folding characteristics of the foldable display device.

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.
