Abstract: A touch detection device includes a substrate, a plurality of drive electrodes arranged on a plane parallel to the substrate and in a first region in which an image is displayed, and a plurality of touch detection electrodes configured to generate a capacitance between the touch detection electrodes and the drive electrodes. At least one touch detection electrode among the touch detection electrodes includes a first part arranged in the first region and a second part arranged in a second region adjacent to the first region. The drive electrodes are sequentially supplied with the first drive signal to detect a conducting body in contact with or close to the first region in a first touch detection mode, and the touch detection electrodes are supplied with a second drive signal to detect a conducting body in contact with or close to the second region in a second touch detection mode.
