Abstract: A light-emitting display device includes first and second sub pixels each of which includes a driving transistor including first and second electrodes and a gate electrode, and being configured to control an electric current flowing from the first electrode to the second electrode according to a data voltage applied to a gate electrode, a light-emitting element connected to the second electrode, and a first capacitor disposed between a first sub supply voltage line to which a first supply voltage is applied and the second electrode. The first sub supply voltage line is disposed to overlap the second electrode. A capacitance of a first capacitor of the first sub pixel versus a capacitance of a first capacitor of the second sub pixel is selectively determined to correspond to an amount of the overlap between the first sub supply voltage line and the second electrode.
