1. A display device comprising:
a display panel including a sub-pixel, the sub-pixel including:
a driving transistor including a gate electrode, a first electrode, and a second electrode;
a light emitting element connected to the second electrode of the driving transistor;
a switching transistor connected to a gate electrode of the driving transistor and configured to supply a data voltage to the driving transistor, and
a sensing transistor connected to a reference line and the second electrode of the driving transistor;
a panel driving circuit configured to supply the data voltage to the switching transistor of the sub-pixel;
a panel sensing circuit configured to sense the sub-pixel; and
a stabilization circuit connected to the reference line and a sensing channel of the panel sensing circuit, the stabilization circuit is turned on while the switching transistor and the sensing transistor are turned on to electrically stabilize the reference line such that charging of a voltage or current in the reference line is performed,
wherein the panel sensing circuit comprises a sampling circuit configured to sense the sub-pixel through the reference line, and
wherein the stabilization circuit comprises a stabilization switch configured to turn on in response to a turn-on operation of a sampling switch included in the sampling circuit.
