1. A display device comprising:
a display panel comprising:
a pixel comprising:
a pixel circuit comprising:
a first thin-film transistor which comprises a gate electrode connected to a first node, a first electrode, and a second electrode, and generates a driving current;
a second thin-film transistor connected between the first electrode of the first thin-film transistor and a data line;
a third thin-film transistor connected between the first node and the second electrode of the first thin-film transistor;
a fourth thin-film transistor connected between the first node and an initialization voltage line;
a fifth thin-film transistor connected between the first electrode of the first thin-film transistor and a first driving voltage line;
a sixth thin-film transistor which controls a transfer of the driving current;
a first capacitor connected between the first node and the first driving voltage line; and
a second capacitor; and
a light-emitting element connected to the pixel circuit,
wherein
the sixth thin-film transistor is connected between the second electrode of the first thin-film transistor and the light-emitting element, and
the second capacitor is connected between a gate electrode of the sixth thin-film transistor and the light-emitting element.
