| titleOfInvention | Electro-optical liquid crystal display |
| abstract | Electro-optical liquid crystal display (LCD) has (a) an orientation layer for orienting the liquid crystal (LC), in which a significant component of the field is parallel to the LC layer, and (b) a LC medium with positive dielectric anisotropy. The novelty is that the medium contains 3,4,5-trifluoro-phenyl compound(s) of formula (I) and trans-4-(1E- or 3E-alkenyl-cyclohexyl compound(s) of formula (II); in which R<1> = hydrogen (H), 1-15 carbon (C) alk(en)yl, optionally mono-substituted by cyano (CN) or trifluoromethyl (CF3) or at least mono-substituted by halogen, in which 1 or more methylene groups (CH2) may be replaced by oxygen (-O-), sulphur (-S-), carbonyl (-CO-), carboxyl (-CO-O- or -O-CO-) or carbonate (-O-CO-O-) without directly linked O atoms; A<1>, A<2> = (a) 1,4-cyclohexenylene or trans-1,4-cyclohexylene (Cyc), in which 1 or more non-adjacent CH2 groups may be replaced by -O- and/or -S-; (b) 1,4-phenylene (Phe), in which 1 or 2 CH groups may be replaced by nitrogen (N); or (c) 1,4-bicyclo(2,2,2)-octylene, piperidin-1,4-diyl, naphth-2,6-diyl, decahydronaphth-2,6-diyl or 1,2,3,4-tetrahydro naphth-2,6-diyl, in which groups (a) and (b) may be mono- or di-substituted by fluorine (F); Z<1>, Z<2> = -CO-O-, -O-CO-, methyleneoxy (-CH2O-), oxymethylene (-OCH2-), ethylene (-CH2CH2-), ethenylene (-CH=CH-), acetylene (-C?=C-) or a single bond and one of Z<1>, Z<2> may also = butylene (-(CH2)4-) or butenylene (-CH=CH-CH2CH2-); m = 0, 1 or 2; R<1>* = 2-7 C 1E- or 3E-alkenyl; R<2>* = F or a 1-6 C alkyl or alkoxy group, optionally at least mono-substituted by F; rings A*, B* = Phe' or Cyc; Phe' = Phe, 2-fluoro-1,4-phenylene (Phe(F)) or 2,6-difluoro-1,4-phenylene (Phe(2F)); I = 0 or 1. |
