Abstract
An orientation layer for a liquid crystal display device is formed from a mixture of at least one reactive liquid-crystal material and at least one non-reactive liquid-crystal material. The mixture is brought into contact with a surface of a mold having an orienting effect, as a result of which the molecules in the mixture are oriented. Subsequently, the reactive liquid-crystal material is made to cure, thereby forming an oriented polymer network in which the non-reactive liquid-crystal material is dispersed. The orientation layer thus manufactured is very suitable for use in an active display device. The liquid crystal device formed has a liquid crystal layer and orientation layers of an oriented polymer network in which liquid crystal material is dispersed.
