According to an aspect, a touch detection device includes: a plurality of drive electrodes arranged in parallel with each other; and a plurality of first touch detection electrodes arranged in parallel with each other and arranged at a portion not in contact with the drive electrodes and where the first touch detection electrode forms capacitance with a drive electrode to which a drive signal is output. The drive electrodes includes a drive electrode including a plurality of subdivided electrodes an arrangement pitch of which is finer than an arrangement pitch of the drive electrodes. The drive electrode including the subdivided electrodes is provided such that switching is enabled between a first mode in which the drive signal is collectively output to the subdivided electrodes of the drive electrode and a second mode in which the drive signal is individually output to each of the subdivided electrodes of the drive electrode.
