Abstract
A touch panel display device includes an active matrix substrate and a control unit. The active matrix substrate is provided with gate lines, pixel electrodes connected to the gate lines, counter electrodes disposed to form a matrix, and touch sensor wires connected to the counter electrodes. The control unit alternately switches, during one frame period, between a gate scan period of scanning the gate lines and a sensor scan period of scanning the counter electrodes by a segment SEG and detecting electrostatic capacitance by. The one frame period includes a plurality of gate scan periods and a plurality of sensor scan periods. The control unit scans each of the segments in a first scan mode of completing touch detection of scanning all the segments in the one frame period a number of times other than an integer.
