1. A light-emitting display apparatus comprising:
a driving transistor electrically connected between a first node and a second node and including a gate electrode connected to a third node;
a switching transistor connected between a data line and the first node and including a gate electrode connected to a scan line;
a first light emission control transistor connected between a first voltage line and the first node and including a gate electrode connected to a light emission control line;
a light-emitting device including an anode electrically connected to the second node and a cathode; and
a capacitor including a first electrode connected to the first voltage line and a second electrode connected to the third node,
wherein the gate electrode of the first light emission control transistor is disposed on a same layer as the first electrode of the capacitor; and
wherein the first light emission control transistor further includes an auxiliary electrode disposed on a same layer as the second electrode of the capacitor and the gate electrode of the switching transistor.
