Abstract: 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 including a block corresponding one-to-one with a light valve data line, and a second electrode facing the first electrode with the liquid crystal layer interposed therebetween. An angle between a vertical edge of the block and the light valve data line is greater than 0° and less than 90°. The liquid crystal display device according to another aspect includes a display panel, a backlight unit, and a light valve panel.
