| titleOfInvention | Liquid crystal media |
| abstract | A liquid crystalline medium containing (A) compound(s) with three 1,4-linked 6-membered rings in which one of the terminal rings is a fluorinated phenyl group and (B) 4-cyano-3-fluorophenyl benzoate derivative(s). A liquid crystalline (LC) medium (I) containing compound(s) of formula (A) and compound(s) of formula (B). Ra, Rb = H, 1-12C alkyl (optionally substituted with one CN or CF3 group or at least one halogen, and optionally with CH2 group(s) replaced by -O-, -S-, cyclobutane-1,3-diyl, -CH=CH-, -Cequivalent toC-, -CO-, -COO-, -OCO- or -OCOO-), -(A)-Z1-(B)-, -Cyc-Z1-Diox- or -Diox-Z1-Cyc-; (A), (B) = rings A, B as above; Cyc = trans-1,4-cyclohexylene; Diox = 1,3-dioxan-5,2-diyl; Z1, Z2 = -CH2CH2-, -(CH2)4-, -CH2-, -(CH2)3- or a single bond; L1-L8 = H or F; Y = F, Cl, SF5, NCS, OCN, SCN or a mono- or poly-halogenated 1-5C alkyl, alkoxy, alkenyl or alkenyloxy group. Independent claims are also included for (1) (1) electro-optical LC displays containing (I) (2) (2) TN or STN LC displays with two base plates forming a cell, a nematic LC mixture with positive dielectric anisotropy (DELTAe) in the cell, electrode layers with orientation layers on the inside of the base plates, an angle of incidence of 0-30 degrees between the base plates and the long axis of the molecules on their surface and a twist angle of 22.5-600 degrees from orientation layer to orientation layer in the cell, in which the nematic LC mixture comprises (a) 15-75 wt% of an LC component A consisting of compound(s) with a DELTAe of more than +1.5, (b) 25-85 wt% of an LC component B consisting of compound(s) with a DELTAe between -1.5 and +1.5, (c) 0-20 wt% of an LC component D consisting of compound(s) with a DELTAe of below -1.5 and (d) optionally an optically active component C in amounts such that the ratio between layer thickness (plate spacing) and natural pitch of the chiral nematic LC mixture = 0.2-1.3, and in which component A contains compound(s) of formula (A) and compound(s) of formula (B) |
