Provided are a method of driving a liquid crystal panel using self-masking, a masking circuit for performing the method, and asymmetric latches. The method includes supplying power to the liquid crystal panel; receiving a horizontal start pulse signal instructing source lines of the liquid crystal panel to be driven, from a timing controller; generating a horizontal start masking signal by masking at least one pulse of the horizontal start pulse signal; and driving the source lines in response to the horizontal start masking signal. The horizontal start masking signal turns off the switches until signals output from the source driver, which correspond to image data of the liquid crystal panel, are supplied. Accordingly, it is possible to prevent unknown image data from being displayed on the liquid crystal display when the liquid crystal panel is powered on.
