A display device having a contact sensing function, and a driving method thereof are disclosed in one embodiment. The driving method of a display device includes reading sense data signals of a current sensing unit row, determining whether the sense data signals are included in a contactable range and converting the sense data signals into preliminary signals that each have a predetermined value based on the determination result, determining whether a sensed area (an X axis sensed area) in an X axis direction exists using the preliminary signals, determining whether the X axis sensed area is effective when the X axis sensed area exists, determining whether a sensed area (a Y axis sensed area) in a Y axis direction exists when the X axis sensed area is effective, determining whether the Y axis sensed area is effective when the Y axis sensed area exists, determining a contact position when the Y axis sensed area is effective, and reading sense data signals of a next sensing unit row when the X axis sensed area or the Y axis sensed area is not effective.
