Title (EN) LIQUID CRYSTAL MEDIUM AND LIQUID CRYSTAL DEVICE
(FR) MILIEU CRISTAL LIQUIDE ET DISPOSITIF À CRISTAUX LIQUIDES
Abstract:
(EN) The invention relates to a medium comprising one or more compounds of formula I, RI11_A11 -A12-(CH2)S-A13-A14-R12 l, in a concentration of up to 30% or less, and one or more compounds of formula II, R21-A21-A22-(A23)U-Z21-(CH2)t-Z22-A24-A25-A26-R22 II, in a concentration of 10% or more, wherein R11 to R22, A11 to A26, Z21, Z22, s, t, and u have one of the meanings as given in claim 1, to a method of production of such a media, to the use of such media in liquid crystal devices, in particular in flexoelectric liquid crystal devices, and to a flexoelectric liquid crystal device comprising a medium according to the present invention.
(FR) L'invention concerne un milieu comprenant un ou plusieurs composés de formule I, RI11_A11 -A12-(CH2)S-A13-A14-R12 l, à une concentration allant jusqu'à 30 % ou moins, et un ou plusieurs composés de formule II, R21-A21-A22-(A23)U-Z21-(CH2)t-Z22-A24-A25-A26-R22 II, à une concentration de 10 % ou plus, dans lesquelles R11 à R22, A11 à A26, Z21, Z22, s, t, et u ont l'une des significations telles que présentées dans la revendication 1, un procédé de production d'un tel milieu, l'utilisation d'un tel milieu dans des dispositifs à cristaux liquides, en particulier dans des dispositifs à cristaux liquides flexoélectriques, et un dispositif à cristaux liquides flexoélectriques comprenant un milieu selon la présente invention.
