    摘要: An electrooptic device (2), and the methods for manufacturing, including a liquid crystal material (12) disposed between electroded flat glass or polymer substrates (4, 20) which have been precoated with a e.g. a chiral smectic surface layer (10, 14) in such way that the surface layer is able to mediate switching of the liquid crystal (12) between different optical states. The chiral smectic surface layer can be a polymer, oligomer or monomer liquid crystal with paraelectric, ferroelectric, ferrielectric or antiferroelectric response, which is insoluble in the liquid crystal used for the bulk (12) between the electroded substrates (4, 20). the switchable surface director enforces a certain orientation of the optic axis in the bulk liquid crystal (12), which can be a conventional non-chiral or chiral nematic or smectic in a twisted or non-twisted configuration.
