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.

Abstract: A video wall-type display device may include: a plurality of display modules, each including: a display area including: a first sub-area; and at least one second sub-area disposed to adjoin and to surround the first sub-area; and a non-display area disposed to surround the display area, wherein the first sub-area may include at least one first pixel unit. The at least one first pixel unit includes: a first pixel configured to display a first color; a second pixel configured to display a second color; and a third pixel configured to display a third colors, the first, second, and third colors being different from each another. The second sub-area may include at least one second pixel unit, the at least one second pixel unit including: the first pixel, the second pixel, and the third pixel; and at least one fourth pixel configured to display a white color.
