Abstract
A display device and a gate driver circuit of the display device are disclosed. The display device includes a shift register that shifts a gate pulse in accordance with a shift clock and sequentially supplies the gate pulse to gate lines. At least one stage of the shift register includes a discharge blocking node connected to a source terminal of the second transistor, and a discharge blocking circuit configured to charge the discharge blocking node when the Q node is charged, and discharge the discharge blocking node when the Q node is discharged.
