Abstract: The organic light-emitting display device comprises a substrate having a folding axis extending in a first direction, the substrate including a folding area configured to curve around the folding axis in a second direction intersecting the first direction; a first anode on the substrate; a bank layer on the substrate; and a plurality of first spacers provided on the bank layer in the folding area and disposed in the second direction. The plurality of first spacers comprises a first-first spacer extending in a direction deviating from the first direction and the second direction when viewed in a plan view; and a first-second spacer spaced apart from the first-first spacer in the second direction and extending in a direction parallel to the direction in which the first-first spacer extends. The first-first spacer and the first-second spacer at least partially overlap each other when viewed in the plan view.

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.
