Disclosed is a liquid crystal display including a liquid crystal panel that includes a plurality of liquid crystal cells for controlling light transmission, a common electrode driving circuit for providing a common voltage signal to a common electrode provided in the liquid crystal panel and a first signal driving circuit for providing a first signal to a transparent electrode provided in the liquid crystal panel. The first signal and the common voltage signal have the same frequency and amplitude, but are out of phase with each other. The transparent electrode is designed to cancel an acoustic noise generated by the application of the common voltage signal. The liquid crystal panel includes two substrates that face each other. In one embodiment, the common electrode and the transparent electrode are formed in the same substrate, and in another embodiment, the common electrode and the transparent electrode are formed in different substrates.
