Abstract
A liquid crystal composition is principally constituted by at least a liquid crystal and a gel-forming compound which forms a gel with the liquid crystal. The gel-forming compound has a discotic liquid crystal phase and assumes a supermolecular structure when it is mixed with the liquid crystal. The supermolecular structure may preferably have at least one intermolecular interacting side having at least one —CONH— group allowing multi-dimensional intermolecular interaction.
Claims9
A liquid crystal device comprising:
- a pair of electrodes and a liquid crystal composition disposed between the electrodes,
- wherein the liquid crystal composition comprises at least a liquid crystal and a gel-forming compound forming a gel with the liquid crystal, said gel-forming compound having a discotic liquid crystal phase, and
- wherein one of the liquid crystal and the gel-forming compound comprises a lower phase transition temperature substance and the other comprises a higher phase transition temperature substance controlling an alignment state of the lower phase transition temperature substance.
