A touch sensor integrated type display device includes a display panel. The display panel includes a multiplexing unit that supplies a common voltage to touch/common electrodes of the display panel during a display driving period of one frame period of the display panel to display an image on the display panel. The multiplexing unit senses the touch/common electrodes using a self-capacitive method during a first touch driving period of the one frame period and a mutual capacitive method during a second touch driving period of the one frame period of the display panel to sense touch of the display panel.
