Touch detection apparatus and display apparatus with touch detection function

A display apparatus with a touch detection function, the display apparatus comprising:

• a display device that displays an image;
• a plurality of drive electrodes arranged in parallel along a display surface on which the image is displayed by the display device, wherein at least one of the drive electrodes includes a plurality of subdivided electrodes arranged at a finer pitch than an arrangement pitch of the drive electrodes;
• a plurality of first touch detection electrodes arranged in parallel along the display surface, wherein each of the first touch detection electrodes outputs a first touch detection signal indicating an electrical change in the first touch detection electrode generated when the touch operation is performed on the display surface at a timing when a drive signal is output to the drive electrodes;
• a second touch detection electrode arranged along a direction intersecting with the subdivided electrode;
• a first shift register circuit in which a plurality of first shift signal output circuits are sequentially coupled to one another, wherein the first shift signal output circuits each generate a signal for sequentially driving the drive electrodes;
• a second shift register circuit in which a plurality of second shift signal output circuits are sequentially coupled to one another, wherein the second shift signal output circuits each generate a signal for sequentially driving the subdivided electrodes;
• and
• a selection circuit that supplies the signal of the first shift register circuit to the drive electrode in a first mode in which the drive electrodes are sequentially driven, and supplies the signal of the second shift register circuit to the subdivided electrode in a second mode in which the subdivided electrodes are sequentially driven.
