Abstract
A sensor device is provided including sensing section including driving electrodes extending in first direction; driving section configured to apply driving voltage to driving electrodes; sensing lines extending in second direction crossing first direction such that sensing lines intersect driving electrodes; and sensing section configured to detect occurrence of electric change from voltage change in at least one of the sensing lines to identify position of occurrence, wherein driving electrodes include a first drive electrode and a second drive electrode, first voltage is applied to at least one first drive electrode, second voltage is applied to at least one second drive electrode, and sensing section identifies position in which object to be detected is in contact or in proximity on a basis of pattern of voltage change of sensing lines, occurring according to difference in manner of intersecting between sensing lines and driving electrodes.
