Abstract: A display device has a gate drive circuit that performs scanning to sequentially supply a gate signal, and a source drive circuit that inverts the polarity of the voltage applied to the source line in each vertical scanning period. The gate drive circuit starts scanning from a first gate line among the plurality of gate lines when scanning the gate lines in a preceding period of two consecutive vertical scanning periods, and starts scanning from a second gate line different from the first gate line when scanning the gate lines in a period following the preceding period of two vertical scanning periods.

Abstract: A plurality of gate bus lines are scanned one by one such that a video signal is written, via a corresponding source bus line, into each of pixel forming sections provided in a plurality of rows and a plurality of columns. When a sensor electrode is driven to detect a touch position, the scanning of the gate bus lines is stopped. Operation of a gate driver and operation of a touch sensor drive circuit are controlled such that, when the sensor electrode is driven, a stop row that is a row at which the scanning of the gate bus lines is stopped is different in each of a first frame period and a second frame period that are two consecutive frame periods.
