Abstract: A gate driver and a display device including the same are discussed. The gate driver includes a plurality of stages. Each stage includes a transistor T1 configured to apply a start signal to a node Q, a transistor Tu configured to output an emission signal of a gate low voltage to a node Na depending on a voltage of the node Q, a transistor T5 configured to control a voltage of a node QB to be reversed to the voltage of the node Q, a transistor Td configured to output the emission signal of a gate high voltage higher than the gate low voltage to the node Na depending on the voltage of the node QB, and a transistor Tbv connected between the transistor T1 and the node Q and configured to stabilize the voltage of the node Q.
