Abstract: A touch detection device includes: drive electrodes that extend in a first direction and are arranged in a second direction intersecting with the first direction; detection electrodes that extend in the second direction and are arranged in the first direction to form capacitance at intersections with the drive electrodes; a driving and scanning unit that sequentially and time-divisionally selects a predetermined number of drive target electrodes to which drive signals are applied from the drive electrodes, and performs driving and scanning at a pitch smaller than a total width of a drive range including the drive target electrodes; and a coordinate correction unit that uses correction information based on a relationship between an input position at which an external object is in proximity to or in contact with a touch detection surface and a detection position detected by the detection electrodes to correct the detection position in the first direction.
