Abstract
Provided is a touch-panel-integrated display device in which influences of noises due to voltages of data lines can be reduced, or noise correction can be easily performed. A touch-panel-integrated display deviceincludes a display panel that has a display area that includes a plurality of pixels defined by a plurality of gate linesand a plurality of data lines. In the display area, a plurality of electrodes, and a plurality of linesconnected with the electrodes, are provided. A predetermined voltage is applied to each lineevery fixed time period, and changes in the capacitance at each electrodeare detected. To each data line, a voltage having a polarity different from that for an adjacent one of the data linesis applied. Each of the electrodesis connected with at least one of the plurality of lines. The at least one of the linesis arranged in the vicinity of a plurality of the data linesto which voltages having different polarities are applied, or alternatively, arranged in the vicinity of one of the data linesto which a voltage having the same polarity as that of a voltage applied to the data linearranged in the vicinity of another lineis applied.
