Abstract:
Provided is a display panel including: a display area; and a gate driver to receive a first clock signal, a first clock bar signal, a second clock signal and a second clock bar signal, the gate driver comprising a first stage and a second stage to respectively apply a first gate voltage and a second gate voltage to the display area, wherein the first clock signal and the first clock bar signal have opposite phases to each other, the second clock signal and the second clock bar signal have opposite phases to each other, the second clock bar signal has phases later than the first clock bar signal, the first stage discharges the first gate voltage based on the first clock signal and a first transfer signal, and the second stage outputs the first transfer signal based on the second clock bar signal.
