Abstract: A display device includes a substrate, first electrodes, second electrodes, and a driver. The first electrodes are disposed in a matrix (row-column configuration) in a display region of the substrate. The second electrodes are disposed in a peripheral region on the outside of the display region of the substrate. The driver supplies a drive signal to the first electrodes and the second electrodes. The first electrodes output detection signals corresponding to self-capacitance changes in the first electrodes. The second electrodes output detection signals corresponding to self-capacitance changes in the second electrodes.
