Kind Code:
B2
Abstract:
Liquid crystalline medium with negative dielectric anisotropy, comprises: (a) a first dielectrically negative component (component A) comprising at least one cyclohexyl derivative (I); and (b) a second dielectrically negative component (component B). Liquid crystalline medium with negative dielectric anisotropy, comprises: (a) a first dielectrically negative component (component A) comprising at least one cyclohexyl derivative of formula (I); and (b) a second dielectrically negative component (component B). R 1>1>, R 1>2>H, unsubstituted alkyl or alkenyl with upto 15C (where at least one CH 2is optionally replaced by -O-, -S-, cyclobutane-1,3-diyl, -CC-, -CF 2-O-, -O-CF 2-, -CO-O- or -O-CO- and O atom is not directly linked with each other); any one of ring of A11-A13 : 2,3-difluoro-cyclohexane-1,4-diyl; or other ring of A11-A13 : cyclohexane-1,4-diyl, cyclohexene-1,4-diyl, 2-fluoro-cyclohexene-1,4-diyl, 2-fluoro-cyclohexene-4,1-diyl, [1,3]dioxane-2,5-diyl, tetrahydropyran-2,5-diyl, benzene-1,4-diyl, 2-fluoro-benzene-1,4-diyl, 2-fluoro-benzene-4,1-diyl or 2,3-difluoro-benzene-1,4-diyl; Z 1>1>, Z 1>2>-CH 2-CH 2-, -CH=CH-, -CC-, -CH 2-O-, -O-CH 2-, -CO-O-, -O-CO-, -CF 2-O-, -O-CF 2-, -CF 2-CF 2- or single bond; X 1>S, Se or Te; and m, n : 0 or 1. Independent claims are also included for: (1) an electro-optical display comprising the liquid crystalline medium as the dielectric; and (2) preparing the liquid crystalline medium, comprising mixing at least one compound (I), at least one compound comprising cyclohexyl derivative of formula (II), (III) or (IV), and/or at least one compound comprising cyclohexyl derivative of formula (IX) and/or at least one further liquid crystalline compound and/or at least one dopant, dye and/or additive.
