ABSTRACT:
A liquid crystal device comprises a layer of a liquid crystal material contained between two spaced-apart cell walls with electrodes for applying an electric field across at least some of the liquid crystal material. At least one of the cell walls includes an alignment structure for inducing a desired local orientation of molecules of the liquid crystal material adjacent thereto. The liquid crystal material includes non-polymerisable low molecular weight surfactant molecules. The invention also provides a liquid crystal composition for use in the device and a method of manufacturing the device.
