Abstract: A liquid crystal display includes: a liquid crystal panel including a liquid crystal layer, a pixel electrode, and a common electrode; and a backlight unit including a light source to provide light to the liquid crystal panel. The pixel electrode includes a longitudinal electrode having a bar shape and extending in a vertical direction; a transverse electrode having a bar shape, crossing the longitudinal electrode, and extending in a horizontal direction; and a branch electrode having a bar shape, extending from the longitudinal or transverse electrode, and including an oblique part extending in an oblique direction. The common electrode overlaps the longitudinal electrode, and a longitudinal opening extending in the vertical direction is defined in the common electrode, and a width of a part of the pixel electrode where the longitudinal and the transverse electrodes cross each other is substantially the same as a width of the transverse electrode.
