The sensing voltage corresponds to the amount of change between the second voltage charged in the sensing electrode Cp1 by the reference voltage wiring Vref and the first voltage corresponding to the charge Cf generated by the touch of the user. When the first signal is interrupted and the first sensor transistor T_S1 is turned off, the second sensor transistor T_S2 is turned on in response to the second signal supplied via the second signal line SN1.
