Abstract: A gate driver circuit and a display device using the same are disclosed. The gate driver circuit includes a first transistor supplying a start signal to a Q node in response to a clock, a second transistor adjusting a gate voltage of the first transistor in response to the clock, a third transistor adjusting a gate voltage of the second transistor in response to the start signal, a fourth transistor changing a voltage of a QB node, a fifth transistor switching a current path between the first transistor and the Q node in response to a first line control signal, a sixth transistor supplying a gate-off voltage to an output node, a seventh transistor supplying a gate-on voltage to the output node, and an eighth transistor supplying a second line control signal to the QB node.
