Zusammenfassung:A gate driving circuit and a light emitting display apparatus comprising the same are discussed, in which a charging characteristic of a control node is improved. The gate driving circuit comprises first to mth stage circuits, wherein each of the first to mth stage circuits includes first to third control nodes, a node control circuit controlling a voltage of each of the first to third control nodes, and an output buffer circuit outputting each of a scan signal, a sense signal and a carry signal in accordance with each of the first to third control nodes, the node control circuit including a node setup circuit charging a first gate high potential voltage in the first control node in response to a first carry signal supplied from a front stage circuit.
