Ferroelectric and Antiferroelectric Liquid Crystals

For the LCDs described above, nematic type of liquid crystalline materials are used. Liquid crystalline materials can be categorized into two large groups nematic [Pg.2]

The FLCs or AFLCs mentioned above are liquid crystalline materials showing a chiral smectic C phase or related phases. Although nematic liquid crystal possesses only directional order, smectic liquid crystals shows layer structures or periodic order of the liquid crystalline molecular centres. In this respect, smectic liquid crystalline materials have more in common with crystalline materials than with nematic liquid crystalline materials. As a result, the alignment of smectic liquid crystal is quite different from that of nematic liquid crystals. Smectic liquid crystals show a large variety of defects because they possesses highly ordered structiu-es. Moreover, the layer structures are irreversibly destroyed by applying stress. This phenomenon poses a major problem for display applications. Therefore, several techniques to prevent the application of force to the liquid crystalline materials of FLC or AFLC devices have been proposed. [Pg.3]

Antiferroelectric LC s with tristable switching have been known for the last ten years120,121. The chemistry of ferroelectric and antiferroelectric liquid crystals follows the rules valid for calamitic LC s, but with some additional constraints ... [Pg.459]
