    Abstract: An exemplary embodiment of the present invention provides a liquid crystal display including a first insulation substrate. A pixel electrode is disposed on the first insulation substrate. A first alignment layer is disposed on the pixel electrode. A second insulation substrate faces the first insulation substrate. A common electrode is disposed on a surface of the second insulation substrate, which the surface of the second insulation substrate faces the first insulation substrate. A second alignment layer is disposed on a surface of the common electrode, which the surface of the common electrode faces the first insulation substrate. A liquid crystal layer is disposed between the first alignment layer and the second alignment layer. The liquid crystal layer includes liquid crystal molecules. Liquid crystal molecules adjacent to at least one of the first alignment layer and the second alignment layer have a pre-tilt angle. At least one of the first alignment layer and the second alignment layer has an ion inductor.

    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.
