    Abstract: According to an aspect, a touch detection device includes a drive unit that supplies an excitation signal having at least variable magnitude to a first electrode at a predetermined period for detecting approach or a touch of an object; a detection unit electrically coupled to a second electrode provided to be opposed to the first electrode to detect approach or a touch of the object according to an output value from the second electrode; and an element that electrically couples the drive unit and the detection unit, receives the excitation signal from the drive unit, and has a predetermined size of electrostatic capacitance. The touch detection device corrects an output value from the second electrode by using an output value from the element and the output value from the second electrode obtained at the same timing.
