摘要： A method, device, and material for providing a fast switching liquid crystal display employs the ferro electric effect of chiral smectic liquid crystal material. To provide a uniform appearance the liquid crystal material is arranged to have a long cholesteric pitch at a temperature close to a smectic/cholesteric phase transistion temperature. This long cholesteric pitch allows liquid crystal molecules to cool from the cholesteric to smectic phase with a uniform alignment. The smectic material is contained in a cell between wells (2, 3) bearing electrodes (5, 6) and surface treated to provide homogeneous alignment of liquid crystal material (7).

摘要： A liquid crystal display is arranged to provide very low minimum light trmission in one of its two switchable states. This makes it useful for a shutter (FIG. 1) and for high contrast digital displays (FIG. 2). A layer of a chiral smectic liquid crystal material is contained between two cell walls carrying electrode structures. The liquid crystal material has the following phases with temperature: isotropic.revreaction.cholesteric.revreaction.chiral smectic.revreaction.solid. The cholesteric pitch is large. The cell walls are surface treated to provide a parallel alignment of liquid crystal molecules. Crossed polarizers are arranged either side of the cell walls, one aligned with its optical axis parallel to the surface alignment of the adjacent cell wall. The device is switched by means of .+-.-d.c. voltage pulses and utilizes the ferro electric effect.
