PROBLEM TO BE SOLVED: To provide a display device including a touch panel, in which detection sensitivity is inhibited from decreasing because of time degradation of a detection electrode.SOLUTION: A display device includes a display panel and a touch panel built in the display panel. The touch panel includes sensitivity correction means for correcting sensitivity of the touch panel. The sensitivity correction means includes: difference acquisition means that acquires a signal difference (S1-S2) between a detection signal S1 obtained by a detection electrode when each scanning electrode receives input of a driving signal having amplitude V1 from driving signal supply means and a detection signal S2 (S1>S2) obtained by the detection electrode when each scanning electrode receives input of a driving signal having amplitude V2 (V1>V2) differing from V1 from the driving signal supply means; and parameter change means that changes a parameter of at least one of the driving signal supply means and detection means when the signal difference (S1-S2) is equal to or below a predetermined threshold. |
