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.

Abstract: A liquid crystal display (LCD) according to an exemplary embodiment of the present invention includes: a first insulation substrate; a lower electrode disposed on the first insulation substrate; a second insulation substrate facing the first insulation substrate; an upper electrode disposed on the second insulation substrate and facing the lower electrode; and a liquid crystal layer disposed between the lower electrode and the upper electrode. The lower electrode forms one unit region, the unit region includes a plurality of subregions, and the lower electrode includes: a first lower electrode including a central pattern disposed at a center of a border between each pair of adjacent subregions, and a plurality of micro branch portions that are coupled to the central pattern, the micro branch portions of two different subregions extending in different directions; and a second lower electrode having intersecting elongated portions that each extend along parts of the border.
