    • A touch sensor includes a touch drive electrode, a touch detection electrode provided opposed to or side by side with the touch drive electrode and forming an electrostatic capacitance between the touch detection electrode and the touch drive electrode, and a touch detection circuit detecting a contact or proximity position of an object on the basis of a detection signal obtained from the touch detection electrode by applying a touch sensor drive signal to the touch drive electrode. The touch drive 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.
