Abstract: A display device includes a display panel including pixels, a touch panel including electrodes, a proximity sensor which is adjacent to the touch panel and detects proximity with respect to an object based on a capacitance variation, a display driver which drives the display panel and a touch controller which drives the touch panel and the proximity sensor. Here, the touch controller provides a negative voltage to the proximity sensor when the proximity sensor detects that the object approaches the proximity sensor such that a shortest distance from the object to the proximity sensor is equal to or less than a first reference distance.
