Abstract: Each gate stage of a gate driver may be implemented to operate based on a clock, a set signal, and a reset signal without a driving power, and thus, may not be connected to the driving power. Accordingly, because a driving power line is omitted, a mount area of the gate driver may be reduced, and thus, a narrow bezel may be easily implemented. Each gate stage may be implemented based on the clock without the driving power, and thus, a configuration thereof may be simplified. In this case, because each gate stage includes a leakage current blocker, even when the gate stage is manufactured based on an oxide transistor having a depletion characteristic, the operation stability thereof may be secured.
