Abstract: A display device includes a display panel foldable about a folding axis, a window on the display panel, a protective film on the window, and a plurality of adhesive layers between the window and the protective film. The adhesive layers include a first adhesive layer on the window and a second adhesive layer on the first adhesive layer. The first adhesive layer includes a side chain crystalline polymer, and the second adhesive layer has a modulus smaller than a modulus of the first adhesive layer.

Abstract: A display device includes a display panel and a sensing panel disposed on the display panel. The sensing panel includes a first conductive layer disposed on a first surface of a base layer, a second conductive layer disposed on the first conductive layer, a first auxiliary conductive layer in a folding region on the same layer as the first conductive layer on the first surface of the base layer, a second auxiliary conductive layer in the folding region on the first auxiliary conductive layer and spaced apart from the second conductive layer, a third conductive layer disposed on a second surface of the base layer, and a fourth conductive layer disposed on the third conductive layer in first and second non-folding regions. The second auxiliary conductive layer is electrically connected to the third conductive layer via a contact hole passing through the first auxiliary conductive layer and the base layer.
