Abstract: A liquid crystal display includes: a first pixel and a second pixel for displaying different colors, the first pixel and the second pixel each including a first sub-pixel electrode receiving a first voltage; a second sub-pixel electrode receiving a second voltage; an insulating layer disposed between the first sub-pixel electrode and the second sub-pixel electrode; and a common electrode receiving a common voltage. A first portion of the first sub-pixel electrode and a second portion of the second sub-pixel electrode overlap each other, a difference between the first voltage and the common voltage is larger than a difference between the second voltage and the common voltage, and a ratio of the second voltage to the first voltage for the first pixel is different from a ratio of the second voltage to the first voltage for the second pixel.

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 curved liquid crystal display including a first curved substrate; a second curved substrate; a liquid crystal layer including liquid crystal molecules having negative dielectric anisotropy, the liquid crystal layer being interposed between the first and second curved substrates; a first curved liquid crystal alignment layer interposed between the liquid crystal layer and the first curved substrate; and a second curved liquid crystal alignment layer interposed between the liquid crystal layer and the second curved substrate. The second curved liquid crystal alignment layer has an average value of surface roughness values greater than an average value of surface roughness values of the first curved liquid crystal alignment layer.
