Abstract:
A display device includes a first substrate, a plurality of first electrodes, a second electrode, a third electrode, and a driver. The first electrodes are disposed in a display region of the first substrate. The second electrode faces the first electrodes in a direction perpendicular to the surface of the first substrate and forms capacitance between the second electrode and the first electrodes. The third electrode is provided in a peripheral region positioned on the outside of the display region and does not overlap the first electrodes in planar view. The driver supplies a drive signal to the third electrode and at least one of the first electrodes simultaneously.
