Abstract
A crystal display deviceincludes TFTs, pixel electrodes, common electrodes, an array board, a CF board, detection electrodes, drive electrodes , a driver, a row control circuit, and a touch controller. The detection electrodes are included in the CF board. The drive electrodes are included in the CF board. The driver and the row control circuit are included in a display driver portion for supplying scan signals and data signals to the TFTs for display driving. The touch controller supplies drive signals to the drive electrodes and detects position detection signals output by the detection electrodes to perform position detection control. The touch controller supplies the drive signals to the drive electrodes to drive the drive electrodes in a scan writing period in which the scan signals are supplied to the TFTs by at least the row control circuit in the display driver portion to drive the TFTs.
