Abstract
A composition, an alignment layer and a method for preparing the same, a liquid crystal alignment unit and a liquid crystal display panel are provided. The composition comprises a nematic liquid crystal polymerizable monomer and a cholesteric liquid crystal polymerizable monomer. The composition can be used for solving the drawbacks existing in the multi-domain display field, such as complex manufacturing processes, high cost, and difficult to be manufactured. The composition allows controlling the alignment of the molecules in the surface of the coating of the composition through adjusting the amounts of the components in the composition and through adjusting the thickness of the coating. The alignment layer, the liquid crystal alignment unit, and the liquid crystal display panel according to the present invention can be prepared by using a simple process and allow to achieve a multi-domain display at a lower cost.
