Smectic liquid crystal devices |
| abstract |
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 ). |
