1. A touch display device, comprising:
a plurality of gate lines;
a plurality of data lines;
a plurality of pixel electrodes connected respectively to the data lines;
a first touch electrode on at least one of the pixel electrodes;
a second touch electrode on at least one of the pixel electrodes and spaced apart from the first touch electrode;
a first signal line connected to the first touch electrode, the first signal line overlapping the second touch electrode without being connected to the second touch electrode; and
a second signal line connected to the second touch electrode, the second signal line overlapping the first touch electrode without being connected to the first touch electrode,
wherein the first signal line and the second signal line are configured to apply touch drive signals respectively to the first touch electrode and the second electrode during a touch driving mode, and
wherein the first signal line and the second signal line are further configured to apply display drive signals different from the touch drive signal respectively to the first touch electrode and the second electrode during a display driving mode.
