A liquid crystal display (LCD) capable of enhancing display quality includes a voltage generation unit, a clock generation unit, a gate driving unit, and a display unit. The voltage generation unit outputs a gate-on voltage and first and second gate-off voltages that are different from each other. The clock generation unit outputs a first clock signal and a second clock signal whose phase is opposite to the phase of the first clock signal. The first clock signal swings between the gate-on voltage and the first gate-off voltage. The gate driving unit is provided with the first clock signal, the second clock signal, and the second gate-off voltage and outputs a gate signal. The display unit includes a plurality of pixels that are turned on or off in response to the gate signal and that display an image.
