PROBLEM TO BE SOLVED: To provide a technique that makes a detection circuit, which is used for a mutual detection, also be used for a self detection, in a touch panel-integrated display device.SOLUTION: A display device comprises a display panel and a touch panel integrated in the display panel. The touch panel has: a plurality of scanning electrodes formed in the display panel; a plurality of detection electrodes that are formed in the display panel and intersect with the plurality of scanning electrodes; drive signal supply means for inputting a drive signal to each of the scanning electrodes; detection means for acquiring a detection signal from each of the detection electrodes; touch position detection means for detecting a touch position of a detection object on the basis of the detection signal detected by the detection means when the drive signal is sequentially input to each of the scanning electrodes from the drive signal supply means; and approach detection means for detecting that the detection object approaches the touch panel on the basis of the detection signal detected by the detection means when a scanning voltage is collectively input to all of the scanning electrodes from the drive signal supply means. |
