Abstract:
A display device includes pixel electrode groups and a touch detection driver. During a period, the touch detection driver does not supply touch detection driving signals to a transmitter electrode overlapping in plan view a pixel electrode group to which gate signals are being supplied, and supply touch detection driving signals to a transmitter electrode disposed so as to overlap in plan view a pixel electrode group to which gate signals are not being supplied.
