Abstract:
There is provided a liquid crystal display, which prevents a blur on a display image by periodically varying a common voltage of the liquid crystal display panel. The liquid crystal display comprises: a liquid crystal display panel having pixel electrodes for supplying data voltages and a common electrode for supplying a common voltage; a common voltage generator for generating common voltages of different potentials; and a common voltage supply unit for periodically changing the potential of a common voltage supplied to the common electrode by switching the common voltages from the common voltage generator.
