Abstract
A liquid crystal display and a method of driving the same are disclosed. The liquid crystal display includes a liquid crystal display panel including data lines and gate lines crossing each other and liquid crystal cells, a timing control signal generating unit, a data drive circuit supplying a data voltage to the data lines, and a gate drive circuit. The timing control signal generating unit generates a first gate timing control signal for controlling a scan direction of the liquid crystal display panel in a sequential direction and a second gate timing control signal for controlling the scan direction in a reverse sequential direction. The gate drive circuit supplies a gate pulse to the gate lines while a shift direction of the gate pulse changes in response to the first and second gate timing control signals.
