Claim 12:
13. The touch display device of claim 1, wherein the touch driving circuit includes:
a differential amplifier which is electrically connected to a first Y-touch line and a second Y-touch line among the plurality of Y-touch lines, and generates an output signal proportional to a difference between a first touch sensing signal received from a first Y-touch electrode line among the plurality of Y-touch electrode lines through the first Y-touch line and a second touch sensing signal received from a second Y-touch electrode line among the plurality of Y-touch electrode lines through the second Y-touch line; and
an integrator for integrating an output signal transmitted from the differential amplifier or integrating a signal in which the output signal is processed.
