Liquid crystal display having function of suppressing stain and method of driving the same

A liquid crystal display and a method of driving the same are disclosed. The liquid crystal display includes a timing signal multiplying circuit generating a first timing signal and a second timing signal whose frequency is higher than a frequency of the first timing signal, a frame counter detecting a multiplied frame period to be driven at the frequency of the second timing signal, a data processing circuit allowing a frequency of digital data output during the multiplied frame period to be higher than a frequency of the digital data output during a frame period except the multiplied frame period, a timing control signal generating circuit generating a polarity control signal for controlling polarities of the digital data, and a polarity control signal inverting circuit that increases a frequency of the polarity control signal during the multiplied frame period to generate an inverse polarity control signal.
