Abstract
A display device includes: a display panel including an upper electrode and an encapsulation layer provided on the upper electrode; a touch panel including a first touch electrode and a second touch electrode each facing the upper electrode and positioned between the display panel and a cover window covering the display panel, the first touch electrode being separated from the second touch electrode; an elastic layer provided on the display panel and deforming in response to an applied pressure from a touch; and a touch sensor programmed to detect an applied pressure from a change in gaps between the first and second touch electrodes and the upper electrode due to the applied pressure, and to detect a capacitance between the first touch electrode and the second touch electrode caused by the touch, so as to sense a position of the touch.
