Abstract: The present disclosure relates to a touch sensor integrated display device capable of preventing generation of a defective image between touch/common electrodes, which includes a plurality of gate lines and a plurality of data lines intersecting the gate lines, a plurality of pixel electrodes, a plurality of touch/common electrodes and a plurality of touch/common lines. The plurality of pixel electrodes are respectively disposed in regions defined by intersections of the plurality of data lines and the plurality of gate lines and provided with data voltages. The plurality of touch/common electrodes are arranged to generate electric fields with the plurality of pixel electrodes and to correspond to parts of the plurality of pixel electrodes. The plurality of touch/common lines are respectively connected to the plurality of touch/common electrodes. Each touch/common electrode overlap with at least one gate line shared by neighboring touch/common electrodes arranged in a data line arrangement direction.
