Abstract: A light valve panel and a liquid crystal display using the same are discussed. The light valve panel according to an embodiment includes a transparent electrode layer having a plurality of blocks supplied with a voltage through data input lines. The transparent electrode layer has a low resistance or has a high resistance. When a transparent electrode layer has low resistance, each block is divided into a plurality of segment electrodes connected through a resistance pattern. A voltage is distributed to the plurality of segment electrodes of each block based on the resistance pattern. When a transparent electrode layer has high resistance, the voltage distribution in each block is based on a resistance difference that varies based on a distance between voltage feeding positions.
