摘要： A liquid crystal display includes a gate driver including stages, and a clock generator which receives a clock generation control signal, generates a clock signal and a clock bar signal based on one or more of the clock generation control signal, a gate-on voltage and a gate-off voltage, and outputs the clock signal and the clock bar signal to the gate driver. The clock generator includes an overcurrent protector unit which intercepts at least one of the clock signal and the clock bar signal when a voltage level of at least one of the gate-on voltage and the gate-off voltage is greater than a reference level.
