A curved liquid crystal display comprises, a first curved substrate; a second curved substrate facing the first curved substrate; a liquid crystal layer disposed between the first curved substrate and the second curved substrate; a first curved liquid crystal alignment layer disposed between the liquid crystal layer and the first curved substrate and containing a light stabilizer; and a second curved liquid crystal alignment layer disposed between the liquid crystal layer and the second curved substrate.

An alignment layer includes at least one of photostabilizers expressed by Formula 1 and Formula 2.

Here, X.sub.1 is H, OH, OR, or R, X.sub.2 is a bond, O, OCO, OR, RO, NOR, or R, X.sub.3 is O, OCO, OR, RO, NOR, or R, each A and B are independently a cyclo-hexyl group, a cyclic ether group, or a phenyl group, each R is independently a C1 to C5 alkyl group, and each m and n are independently a natural number of 0 to 2.

An object of the invention is to provide polymerizable compounds having excellent optical characteristics and suited as materials for optically anisotropic articles, compositions containing the polymerizable compounds, polymers obtained by polymerising the polymerizable compounds, optically anisotropic articles formed of the polymers, and liquid crystal display devices including the optically anisotropic articles.

The present disclosure provides curable compositions comprising one or more of polymerizable liquid crystalline compounds or polymerizable polyesters with disrupted crystallinity, as well as polymeric materials formed from the curable compositions. Further provided herein are methods of producing the compositions and using the same for the fabrication of medical devices, such as orthodontic appliances.
