Abstract: A display device for performing a sensing operation according to an embodiment of the present inventive concept includes a pixel unit including pixel circuits each including a light emitting element, a driving transistor, a switching transistor, and a sensing control transistor connected between an anode electrode and an initialization power source; a scan driver connected to the pixel circuits through horizontal lines and sequentially outputting scan signals and sensing control signals; and a sensing unit configured to sense voltages or current of first nodes each disposed between an anode electrode and a driving transistor. The scan driver simultaneously outputs the sensing control signals to the horizontal lines at every predetermined discharge cycle.
