    Abstract: A display device includes a flexible display panel, a sensing scan driver, and a sensing signal processor. The display panel includes a plurality of flexible touch input electrodes arranged in a first direction and a plurality of flexible touch output electrodes arranged in a second direction. The sensing scan driver supplies sensing input signals to the flexible touch input electrodes. The sensing signal processor receives sensing output signals through the flexible touch output electrodes. The display panel includes a plurality of touch sensing areas. One of the touch input electrodes and a pair of the touch output electrodes correspond to one of the touch sensing areas when the display panel stretches in the first direction by a predetermined first threshold value or more.
