Claim:
1. A touch sensor comprising: a sensor electrode having an electrostatic capacitance for touch detection; a touch detection circuit that performs a detection of a contact or proximity position of an object, on the basis of a detection signal obtained from the sensor electrode by applying a touch sensor drive signal to the sensor electrode, wherein the sensor electrode is split into a plurality of electrode patterns in a stripe shape, and application of the touch sensor drive signal to part of the plurality of electrode patterns causes a drive line to be formed at that time, the touch detection circuit performs the detection on the basis of a first detection signal obtained from a first drive line formed in a first period, and a second detection signal obtained from a second drive line formed in a second period different from the first period, and the touch detection circuit performs the detection on the basis of a differential signal between the first detection signal and the second detection signal.
