Abstract
Provided is a touch panel device configured to execute touch panel drive processing while appropriately preventing discoloration of a semi in-cell touch panel. A touch panel-equipped display deviceincludes a touch panel TP and a touch panel controller. The touch panel TP is configured as a semi in-cell touch panel, and includes a color filter layer, a sense electrode layer provided with sense electrodes RxRx, and a drive electrode layer provided with drive electrodes Txto Tx. The sense electrode layer and the drive electrode layer oppose each other with the color filter layer interposed therebetween. The touch panel controllergenerates a drive signal such that an integrated value of a potential difference between the drive electrode and the sense electrode is less than a first value in a predetermined period of driving the touch panel.
