Abstract: A touch sensor includes a sensor electrode having an electrostatic capacitance for touch detection, and a touch detection circuit detecting 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. The sensor electrode is split into plural stripe-like electrode patterns. Applying the touch sensor drive signal to part of the electrode patterns forms a drive line at that time. The touch detection circuit performs a 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.
