    Abstract: A curved liquid crystal display is provided. The curved liquid crystal display includes: 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 first curved liquid crystal alignment layer includes protrusions protruded toward the second curved liquid crystal alignment layer. The second curved liquid crystal alignment layer includes protrusions protruded toward the first curved liquid crystal alignment layer. An average number of the protrusions on the second curved liquid crystal alignment layer is greater than an average number of protrusions on the first curved liquid crystal alignment layer.
