Abstract
A liquid crystal display and a method of driving the same are disclosed. The liquid crystal display includes a data drive circuit that supplies a data voltage, whose a polarity is periodically inverted, to the data lines, a gate drive circuit, and a timing controller. The gate drive circuit sequentially supplies a first gate pulse synchronized with a first data voltage to gate lines, and sequentially supplies a second gate pulse synchronized with a second data voltage having a polarity opposite a polarity of the first data voltage, to the gate lines. The timing controller generates a pre-gate start pulse for controlling an output of the first gate pulse during a blank period, and then generates a real gate start pulse for controlling an output of the second gate pulse during an initial period of a frame period following the blank period.
