Touch sensor integrated type display device

A touch sensor integrated type display device comprising:

• a plurality of gate lines;
• a plurality of data lines crossing over the plurality of gate lines;
• a plurality of pixel electrodes to which data signals are supplied through the plurality of data lines;
• a plurality of touch/common electrodes;
• a plurality of touch/common routing wires connected to the plurality of touch/common electrodes to supply a common voltage and a touch driving signal based on a time division method of time-dividing one frame period into a display operation period and a touch operation period;
• and
• a plurality of dummy routing wires transversing the plurality of touch/common electrodes in an active area of the display device and arranged in the same direction with the plurality of touch/common routing wires, the plurality of dummy routing wires not connected to the plurality of touch/common electrodes in the active area,
• wherein the common voltage is supplied to the plurality of touch/common routing wires during the display operation period,
• wherein the touch driving signal is supplied to the plurality of touch/common routing wires during the touch operation period and a load free driving signal is supplied to the plurality of dummy routing wires during the touch operation period, and
• wherein the load free driving signal either is the same as the touch driving signal, or has the same phase and amplitude as the touch driving signal.
