Liquid crystal device and method its fabrication

• The invention relates to a liq. crystal device comprising a liq. crystal bulk layer and a surface-director alignment layer comprising side-chains arranged to interact with the bulk layer, wherein the orientation of the bulk layer mols. and the orientation of said side-chains each is directly controllable by an elec. field via dielec. coupling, thus resulting in a decreased total time period (rise and decay times) needed to switch and relax the liq. crystal bulk mols. in response to an applied external field. The invention also relates to a method for manufg. a liq. crystal device and a method of controlling a liq. crystal bulk layer.
