1. A display device comprising:
a display panel including a plurality of pixels;
a data driver configured to drive the display panel; and
a gate driver configured to supply a scan signal and an emission control signal to the display panel,
wherein the plurality of pixels includes:
a light-emitting element including an anode electrode, a cathode electrode, and a multilayer-based organic compound stack between the anode electrode and the cathode electrode;
a driving transistor configured to drive the light-emitting element; and
a plurality of switching transistors configured to drive the driving transistor,
wherein each of the plurality of pixels is driven by scan signals output from the same gate driver and a one emission control signal,
wherein the plurality of switching transistors comprise:
a sampling transistor connected to a first node of the driving transistor and a second node of the driving transistor;
a second transistor connected to a data line and a fourth node of the driving transistor;
a third transistor connected to the fourth node of the driving transistor and an input of a high-level driving voltage;
an emission transistor connected to the second node of the driving transistor and a third node of the light-emitting element;
a first initial transistor connected to the first node of the driving transistor and an input of an initialization voltage;
a second initial transistor connected to the input of an initialization voltage and the third node of the light-emitting element; and
a capacitor connected to the first node of the driving transistor and the input of the initialization voltage.
