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.

Abstract: Disclosed are a stretchable touchscreen, a method for manufacturing the same and a display device including the same. After using a material having a high elastic restoring force as a substrate and determining regions where touch electrodes are formed by defining grooves thereon, touch electrodes are formed by filling the grooves with nanowires. Accordingly, it is possible to maintain elastic restoring force of the substrate and electrical connection between wires of nanowires, so that the touch electrode neither breaks nor factures despite being stretched any direction, and reliable stretchable touchscreens can be provided due to no resistance increase.
