A liquid crystal display wherein power consumption of a gate drive circuit is reduced and a method of driving the same are disclosed. The liquid crystal display includes a liquid crystal panel having pixel regions defined by intersection of a plurality of gate lines and a plurality of data lines, a timing controller to output a clock pulse selectively having a first voltage level, second voltage level and third voltage level of different voltage levels and a data control signal, a gate drive unit to drive the gate lines in response to the clock pulse, and a data drive unit to drive the data lines in response to the data control signal.
