Abstract

A touch display device capable of reducing the width of a bezel area and achieving a slim device while arranging touch type button keys in the bezel area. The touch display device may be an in-cell touch display device that include at least one touch electrode located on a cover glass, corresponding to one or more touch key areas separated at intervals in a bezel area, extended to a display area and overlapping with a common electrode neighboring the touch key area from among the plurality of common electrodes. Accordingly, when a touch key area is touched, the voltage of a common electrode overlapping the touch electrode changes to sense whether the touch key area is touched, and thus there may not be a need to provide an additional touch panel and an additional touch driving circuit to the bezel area.
