Abstract: A display device, including: a touch screen panel including a touch panel and a display panel stacked under the touch panel; a touch driving circuit; and one or more rollers on which at least a portion of the touch screen panel is rolled. The touch panel may include receiving electrodes extending in a first axis direction and arranged in parallel in a second axis direction perpendicular to the first axis direction and driving electrodes extending in the second axis direction and arranged in parallel in the first axis direction. The display panel may include gate lines and source lines intersecting with the gate lines. The touch driving circuit may be configured to apply driving signals to the driving electrodes. The touch screen panel rolled on the one or more rollers may be unfolded as the one or more rollers slide in the first axis direction.
