Light valve panel and liquid crystal display using the same

A light valve panel and a liquid crystal display using the same are discussed. The light valve panel according to an aspect includes a liquid crystal layer, a first electrode receiving a light valve data voltage through a light valve data line, and a second electrode facing the first electrode with the liquid crystal layer interposed therebetween, and receiving a common voltage swinging in the same phase in synchronization with the light valve data voltage.
