Abstract
A technology which can improve the accuracy of touch detection is proposed. A display device includes: a touch panel including plural drive electrodes and plural detection electrodes; plural peripheral wirings; and plural switching elements each of which is disposed between a detection electrode and the corresponding peripheral wiring and that is connected to the detection electrode and the corresponding peripheral electrode. The touch panel executes detection by means of a mutual detection scheme using the plural drive electrodes and the plural detection electrodes. In a condition in which a predefined voltage is applied to the peripheral wirings when the plural switching elements are in an off-state, the voltages of the drive electrodes are changed, and subsequently a condition in which the changes of the voltages of the drive electrodes can be detected from the peripheral wirings is set, and the switching elements are turned from off to on.
