A photopolymer mixture is capable of use for a liquid crystal alignment layer. An alignment layer is formed from such a photopolymer mixture. The mixture comprises at least two polymerisable materials which are blended together in proportion so as to give a predetermined, preferably low, surface energy. A low surface energy, e.g., less than 410

Zenithal Bistable LCDs use a standard twisted-nematic geometry but with a surface-relief grating as one of the alignment layers. Best operation results from operating in a normally white-TN mode. An improved white state is possible by tuning the cell gap. The consequences of this change on device performance and cost are discussed. Source
