LIQUID CRYSTALLINE COMPOUND, LIQUID CRYSTAL COMPOSITION, AND LIQUID CRYSTAL DISPLAY ELEMENT

The invention provides a liquid crystal compound having stability to heat, light and so forth, a wide temperature range of a nematic phase, a small viscosity, a suitable optical anisotropy, a suitable elastic constant K33, a suitable and negative dielectric anisotropy, and an excellent compatibility with other liquid crystal compounds. The invention provides a liquid crystal composition containing the compound described above and having stability to heat, light and so forth, a small viscosity, a suitable optical anisotropy, a suitable and negative dielectric anisotropy, a suitable elastic constant K33, a low threshold voltage, a high maximum temperature of a nematic phase, and a low minimum temperature of the nematic phase. The invention also provides a liquid crystal display device having a short response time, a small power consumption, a low driving voltage, and a large contrast, and containing the composition described above which can be used in a large temperature range. For example, a liquid crystal compound having four or more rings in which the central ring has 2,3-difluorophenoxy such as trans-4'-[2,3-difluoro-4-(trans-4-propylcyclohexyl)phenoxymethyl]-trans-4-pentylbicyclohexyl is provided. Further provided is a liquid crystal composition containing the compound, and a liquid crystal display device using this liquid crystal composition.

Substituted Terminal Alkyl Groups and Their Prospects in Liquid Crystal Chemistry

Polar substituents may be attached to the terminal alkyl groups of rodlike mesogens to increase their ε and to give a positive or negative Δε.The mesomorphic behaviour of some biphenyls, phenylcyclohexanes and bicyclohexanes with substituted alkyl groups was studied and compared to that of the corresponding unsubstituted compounds.In the first series no conclusive results could be obtained due to the relatively high melting points and low clearing points of the investigated compounds.In the phenylcyclohexanes and bicyclohexanes, substituents in ω-position were found to enhance the clearing temperature.In contrast, cyano groups in α-position depressed the clearing point.However, this depression is still much less than that caused by the introduction of lateral substituents in the phenyl moieties of the rigid core.
