Title (EN) LIQUID CRYSTAL MEDIUM AND LIQUID CRYSTAL DEVICE
(FR) MILIEU À CRISTAUX LIQUIDES ET DISPOSITIF À CRISTAUX LIQUIDES
Abstract:
(EN) The invention relates to a compound of formula (I), R11-MG11-X11-Sp11-X12-MG12-R12 wherein R11, R22, MG11, MG12, Sp11, X11 and X12 have one of the meanings as given herein below. The invention further relates to method of production of a compound of formula I, to the use of said compounds in LC media and to LC media comprising one or more compounds of formula I. Further, the invention relates to a method of production of such LC media, to the use of such media in LC devices, in particular in flexoelectric LC devices and to a flexoelectric LC device comprising a LC medium according to the present invention. P16272 SL -118- Abstract The invention relates to a compound of formula (I), R 11 -MG 11 -X 11 -Sp 11 -X 12 -MG 12 -R 12 I wherein R 11, R 22, MG 11, MG 12, Sp 11, X 11 and X 12 have one of the meanings as given herein below. The invention further relates to method of production of a compound of formula (I), to the use of said compounds in LC media and to LC media comprising one or more compounds of formula (I). Further, the invention relates to a method of production of such LC media, to the use of such media in LC devices, in particular in flexoelectric LC devices and to a flexoelectric LC device comprising a LC medium according to the present invention.
