Abstract
A display device, includes: a base substrate; a display element layer on the base substrate, the display element layer including a driving electrode; an insulation layer on the display element layer, the insulation layer defining an active region and a peripheral region adjacent to the active region; an input sensing layer on the insulation layer, the input sensing layer including a sensing electrode that overlaps the active region and a compensation electrode that overlaps the peripheral region, the sensing electrode and the driving electrode forming a parasitic capacitor; and a detection control circuit electrically connected through an output node to the sensing electrode and the compensation electrode, wherein the detection control circuit is configured to control a capacitance of the parasitic capacitor using a first offset capacitor, the first offset capacitor being formed by the compensation electrode.
