Abstract: A manufacturing method of an adhesive layer includes: providing a preliminary adhesive layer, attaching a mask to a first area portion of the preliminary adhesive layer, and thereby, provide a second area portion of the preliminary adhesive layer that is adjacent to the first area portion and to which the mask is not attached, to provide an adhesive layer that exhibits good folding reliability. In addition, a display device may exhibit good folding reliability characteristics by including the adhesive layer from which an adhesion force of a folding area is reduced between a supporting member and a display panel of the display device.

Abstract: Provided is a display device. The display device comprises a functional layer in which a plurality of pixel areas are defined and which includes at least one coil to which an AC signal is applied and an input sensor configured to sense an input from an external source and disposed on the functional layer. The input sensor comprises a first conductive layer including a first sensing loop extending in a first direction, a sensing insulation layer disposed on the first conductive layer, and a second conductive layer disposed on the sensing insulation layer and including a second sensing loop extending in a second direction crossing the first direction.
