Claim Text:
1. A display device comprising: an electrode shared by a display electrode and a touch sensing electrode; and a drive circuit configured to drive the electrode, wherein: the drive circuit is configured of a single-channel thin film transistor and includes a first thin film transistor connected to the electrode and a second thin film transistor connected to the electrode; the first thin film transistor has a terminal to which a first signal is inputted, and a gate electrode to which control signal is applied when transmitting the first signal to the electrode, the second thin film transistor has a terminal to which a second signal is inputted, and a gate electrode to which control signal is applied when transmitting the first signal to the electrode, the first thin film transistor conducts electricity when using the electrode for sensing a touch and transmits the first signal to the electrode; the second thin film transistor conducts electricity when using the electrode for display and transmits the second signal to the electrode; and a voltage of the control signal when the first thin film transistor transmits the first signal is greater than a voltage of the control signal when the second thin film transistor transmits the second signal.
