1. A touch display device comprising:
a first electrode and a second electrode which are installed inside a display panel and face each other to form a capacitance;
a first coil installed inside the display panel and connected to the first electrode and the second electrode; and
a second coil installed inside the display panel and having a mutual induction with the first coil to generate a current in the second coil by the mutual induction,
wherein the touch display device conducts a touch detection by the generated current,
wherein when the capacitance is changed, a current flows in the first coil to produce a magnetic field from the first coil, and
wherein the current of the second coil is generated by the magnetic field from the first coil.
