Abstract: Disclosed is an in-cell touch type touch display device in which the number of touch lines is reduced to increase a transmittance, and the number of touch integrated circuits (ICs) is reduced to lower the manufacturing cost. The touch display device includes a touch display panel and a driving circuit unit. A plurality of touch sensors may be disposed in the touch display panel, and a plurality of subpixels including a common electrode may be provided between the plurality of touch sensors. The subpixels may be provided between the plurality of touch sensors which are adjacent to each other in a horizontal direction and a vertical direction. The driving circuit unit may include a touch driver, a touch sensing unit, and a power supply. The touch driver may supply a touch driving signal to the plurality of touch sensors.
