1. A liquid crystal switching device comprising:
- (a) a first substrate having a first surface;
(b) a redox-active material disposed on a first portion of the first surface, the redox-active material comprising at least one redox-active group;
(c) a liquid crystal disposed above the redox-active material; and
(d) a salt dispersed in the liquid crystal, wherein the liquid crystal changes from a first orientation to a second orientation with respect to the first surface of the substrate when an oxidation state of the at least one redox-active group is changed from a first oxidation state to a second oxidation state.

Abstract
The invention provides liquid crystal switching devices, liquid crystal cells made from the switching devices, and electrooptical cells made from the switching devices. The invention further provides methods for methods for changing the orientation of a liquid crystal in a liquid crystal switching device. The liquid crystal switching devices are constructed from a redox-active material supported by a substrate and a liquid crystal having a salt dispersed therein disposed atop the redox-active material.
