Abstract: A light-emitting display device includes a first transistor including a driving gate electrode, a first electrode, and a second electrode, a storage capacitor including a first electrode and a second electrode connected to the driving gate electrode, a second transistor connected to the second electrode of the storage capacitor, a first hold capacitor including a first electrode connected to the second electrode of the storage capacitor and a second electrode to which a driving voltage is applied, a second hold capacitor including a first electrode connected to the second electrode of the storage capacitor and a second electrode to which a driving voltage is applied, a third transistor connecting the driving gate electrode and the second electrode of the first transistor, and a light-emitting diode. Conductive layers in which the first electrode of the first hold capacitor and the first electrode of the second hold capacitor are disposed are different.
