1. An emissive display device comprising:
a driving transistor that includes a driving gate electrode, a first electrode, and a second electrode;
a storage capacitor that includes a first electrode electrically connected to the driving gate electrode and a second electrode;
a hold capacitor that includes a first electrode electrically connected to the second electrode of the storage capacitor and a second electrode to which a driving voltage is applied;
a light emitting diode that includes an anode; and
a connector that directly electrically connects the first electrode of the hold capacitor and the second electrode of the storage capacitor, wherein
the first electrode of the hold capacitor is disposed in a first gate conductive layer,
the second electrode of the storage capacitor is disposed in a second gate conductive layer different from the first gate conductive layer, and
the connector is disposed in a first data conductive layer disposed on the first gate conductive layer and the second gate conductive layer.
