    Abstract: A display device includes the following elements: a light emitting diode; a first transistor including a drain electrode, a source electrode, and a gate electrode, the drain electrode being connected to the light emitting diode; a second transistor connected between a data line and the source electrode; a third transistor connected between the drain electrode and the gate electrode; and a fourth transistor connected between a first initialization voltage source and the gate electrode. The third transistor is off for a first period, on for a second period immediately following the first period, and off for a third period immediately following the second period. The fourth transistor is off for a fourth period, on for a fifth period immediately following the fourth period, and off for a sixth period immediately following the fifth period. The second period overlaps the fifth period.

    Abstract: The present disclosure relates to a display device that can reduce a difference between the load connected to scan lines around a notch area and the load connected to scan lines in the entire display area. According to an embodiment of the disclosure, a display device comprising a display panel comprising a display area that includes a first display area, and a second display area and a third display area disposed adjacent to the first area, a touch detector, a scan driver circuit, and a touch driver circuit supplying a touch driving signal to touch electrodes of the touch detector, wherein the touch driver circuit changes a pulse width or an output timing of the touch driving signal while images are displayed on at least one of the first to third display areas and supplies the touch driving signal to the touch electrodes.
