1. A light-emitting display device, comprising:
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 thea driving voltage is applied;
a third transistor connecting the driving gate electrode and the second electrode of the first transistor;
a light-emitting diode including an electrode;
a fourth transistor which initializes a voltage of the driving gate electrode to a first initialization voltage; and
a seventh transistor which initializes a voltage of the electrode of the light-emitting diode to a second initialization voltage,
wherein 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 from each other.
