1. A display device comprising:
a first sub pixel emitting light of a first color; and
a second sub pixel emitting light of a second color,
wherein each of the first sub pixel and the second sub pixel comprises:
a driving transistor including a first electrode, a second electrode, and a gate electrode, the driving transistor configured to control an electric current flowing from the first electrode to the second electrode according to a data voltage applied to the gate electrode;
a light-emitting element connected to the second electrode of the driving transistor;
a first capacitor including a first electrode connected to a first sub supply voltage line to which a first supply voltage is applied and a second electrode connected to the second electrode of the driving transistor; and
a second capacitor including a first electrode connected to the gate electrode of the driving transistor and a second electrode connected to the first sub supply voltage line, wherein
an area where the first electrode of the first capacitor overlaps the second electrode of the first capacitor in the first sub pixel is different from an area where the first electrode of the first capacitor overlaps the second electrode of the first capacitor in the second sub pixel, and
an area where the first electrode of the second capacitor overlaps the second electrode of the second capacitor in each of the first sub pixel and the second sub pixel is larger than the area where the first electrode of the first capacitor overlaps the second electrode of the first capacitor in each of the first sub pixel and the second sub pixel.
