Title (DE) FLÜSSIGKRISTALLINES MEDIUM
(EN) LIQUID CRYSTAL MEDIUM
(FR) MILIEU CRISTAL LIQUIDE
Abstract:
(DE) Die Erfindung betrifft ein flüssigkristallines Medium mit negativer dielektrischer Anisotropie, welches mindestens eine Verbindung der Formel (I), worin R1, R1* und a die in Anspruch 1 angegebenen Bedeutungen haben, enthält, sowie seine Verwendung für eine Aktivmatrix-Anzeige, insbesondere basierend auf dem VA-, PS-VA, PALC-, FFS- oder IPS-Effekt.
(EN) The invention relates to a liquid crystal medium having negative dielectric anisotropy, comprising at least one compound of the formula (I), where R1, R1*, and a have the meanings indicated in Claim 1, and to the use thereof for an active matrix display, particularly based on the VA, PS-VA, PALC, FFS, or IPS effect.
(FR) L'invention porte sur un milieu cristal liquide avec une anisotropie diélectrique négative, lequel comprend au moins un composé de formule (I), où R1, R1* et a ont les significations indiquées dans la revendication 1, ainsi que sur son utilisation pour un dispositif d'affichage à matrice active, en particulier sur la base de l'effet VA, PS-VA, PALC, FFS ou IPS.
