Abstract
A gate driving circuit and a light emitting display apparatus including the same are disclosed, in which current leakage of a control node may be avoided. The gate driving circuit includes first to mth stage circuits, wherein each of the first to mth stage circuits includes first to fifth control nodes, a node control circuit controlling a voltage of each of the first to fourth control nodes based on a first front carry signal, a sensing control circuit controlling a voltage of the fifth control node based on a line sensing preparation signal, a second front carry signal and a first reset signal, and a first node reset circuit controlling the voltage of the first control node based on the voltage of the fifth control node and a second reset signal, wherein the first node reset circuit may include a discharge path having two thin film transistors connected between a gate low potential voltage line and the fifth control node.
