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.
