Abstract
(DE)
Die Erfindung betrifft ein flüssigkristallines Medium auf der Basis eines Gemisches von polaren Verbindungen mit positiver dielektrischer Anisotropie, dadurch gekennzeichnet, daß es eine oder mehrere Verbindungen der allgemeinen Formel (I) enthält, worin R, A1, A2, Z1, Z2, Y, L1 und m die in Anspruch 1 angegebene Bedeutung haben.
(EN)
A liquid crystal medium based on a mixture of polar compounds with positive dielectric anisotropy is characterised in that it contains one or several compounds having the general formula (I), in which R, A1, A2, Z1, Z2, Y, L1 and m have the meanings given in the first claim.
(FR)
Un milieu à cristaux liquides à base d'un mélange de composés polaires à anisotropie diélectrique positive se caractérise en ce qu'il contient un ou plusieurs composés de la formule générale (I), dans laquelle R, A1, A2, Z1, Z2, Y, L1 et m ont la signification donnée dans la première revendication.
