Abstract: In one embodiment, a touch-detection device includes first and second sensors, a driver and a detection circuit. The driver supplies a driving signal to the first and second sensors. The detection circuit detects an object which is in contact with a detection area, based on a detection signal which is read from the first and second sensors. The driver simultaneously supplies the signal to the first sensors in a first period, simultaneously supplies the signal to the second sensors in a second period following the first period, when the object was not detected in the first period, and successively supplies the signal to the respective first sensors in the second period, when the object was detected in the first period.
