Abstract
A gate driver includes: a shift register and a gate signal generating unit. The shift register unit sequentially outputs scanning signals. The gate signal generating unit generates a normal gate signal and an inverted gate signal based on the scanning signals, controls a charge sharing operation of the normal gate signal and the inverted gate signal, and generates an output gate signal having a rising edge and a falling edge at which a voltage level of the output gate signal is increased and decreased by a charge sharing voltage.
