    Abstract: Disclosed is a novel liquid-crystalline compound which is a naphthalene derivative useful as an electro-optical liquid crystal display material, a liquid crystal composition containing such naphthalene derivatives and a liquid crystal display device comprising the same. The naphthalene derivative provided by the present invention exhibits an excellent liquid-crystallinity and miscibility with currently widely used liquid crystal compositions or compositions. The addition of the naphthalene derivative makes it possible to drastically lower the threshold voltage of the liquid crystal composition while maintaining its high response. The naphthalene derivative of the present invention is characterized by a large birefringence index. Further, most of the naphthalene derivative of the present invention has no strongly polar group in its molecule and thus can also be used for active matrix driving.

  • Patent number: 4723005
    Abstract: New anisotropic compounds of the formula (1) are useful in liquid crystal mixtures for electrooptical displays; at least one of the end groups of the compounds (1) is an alkyl group which carries cyano or halogen in a terminal or non-terminal position. This offers advantages for longitudinal polarization and/or cross-polarization of the anisotropic compounds with the aid of the comparatively highly polarizing cyano or halogen substituents, in particular high clear points, low .DELTA..epsilon./.epsilon..perp. values and/or negative .DELTA..epsilon. values.

  • Patent number: 4686289
    Abstract: New anisotropic compounds with a cross-polarizing substituent have the formula (1) ##STR1## The increase in .epsilon..perp. is achieved by the polarizing group X, preferably the cyano group or a halogen atom, which is not laterally on the ring, as with the known compounds, but is on the bridge, that is to say is part of the main bridge bonding rings A and B to one another. Ring A has the formula (1a) or (1b) given herein and is always cycloaliphatic, while ring B can be identical to ring A or is an aromatic ring of the formula (1c) or (1d) herein. R.sup.1 and R.sup.2 are identical or different end groups of the formula (1e) herein.The radical X on the bridge causes less widening of the molecule than a radical X on a ring, which provides comparatively higher clear points and moreover enables aromatic rings to be omitted from the anisotropic compounds.
