Abstract
According to an aspect, a display device includes: a first substrate; a second substrate facing the first substrate; a display function layer between the first substrate and the second substrate and displaying an image; first electrodes in a detection region of the first substrate; second electrodes in the detection region above the second substrate; a first electrode selection circuit in a peripheral region outside the detection region of the first substrate; and a second electrode selection circuit in a region overlapping with the peripheral region above the second substrate. The first electrode selection circuit selects some of the first electrodes, and supplies detection drive signals having phases determined on the basis of a certain code to the selected first electrodes. The second electrode selection circuit selects some of the second electrodes on the basis of a certain code, and couples the selected second electrodes to a single output signal line.
