Proposed is a gate driver and a display device having the same. The gate driver includes a plurality of stage circuits, wherein each of the plurality of stage circuits includes a shift register configured to control charging and discharging of a Q node and a QB node, and a plurality of output buffers sequentially connected to the shift register, wherein each of the output buffers includes a first transistor configured to transmit a voltage of the Q node to a Q′ node, a pull-up transistor configured to output a clock signal to a gate line in response to a voltage of the Q′ node, and a pull-down transistor configured to output a low-potential voltage to the gate line in response to a voltage of the QB node.
