Title (EN) LIQUID CRYSTAL COMPOUNDS HAVING FLUORINATED LINKAGES, LIQUID CRYSTAL COMPOSITIONS, AND LIQUID CRYSTAL DISPLAY DEVICES
(FR) COMPOSES DE CRISTAUX LIQUIDES COMPORTANT DES LIAISONS FLUOREES, COMPOSITIONS DE CRISTAUX LIQUIDES ET DISPOSITIFS D'AFFICHAGE A CRISTAUX LIQUIDES
Abstract: front page image
(EN)Liquid crystal compounds of general formula (1) which have a low threshold voltage and a low viscosity and are excellent in compatibility with other liquid crystal compounds particularly at low temperature; liquid crystal compositions containing the compounds; and liquid crystal display devices made by using the compositions: wherein R?1¿ and R?2¿ are each alkyl or the like; A, B, C and D are each 1,4-cyclohexylene or the like; Z?1¿ and Z?2¿ are each -(CH¿2?)¿2?- or the like; m and n are each 0 to 2; q and r are each 1 to 2; and o and p are each 0 to 2 with the proviso that o and p must satisfy the relationship: o + p = 2.
(FR)Cette invention se rapporte à des composés de cristaux liquides représentés par la formule générale (1) qui possèdent une tension de seuil basse et une faible viscosité et offrent une excellente compatibilité avec d'autres composés de cristaux liquides, notamment à basse température. L'invention concerne également des compositions de cristaux liquides contenant ces composés ainsi que des dispositifs d'affichage à cristaux liquides fabriqués avec ces compositions. Dans la formule (1), R?1¿ et R?2¿ sont chacun alkyle ou analogue, A, B, C et D sont chacun 1,4-cyclohexylène ou analogue, Z?1¿ et Z?2¿ sont chacun -(CH¿2?)¿2?- ou analogue, m et n sont chacun compris entre 0 et 2, q et r sont chacun compris entre 1 et 2, et o et p sont chacun compris entre 0 et 2 et doivent satisfaire la relation o + p = 2.
