titleOfInvention | COMPOSITION OF NEMATIC LIQUID CRYSTALS. |
abstract | A composition of nematic liquid crystals, in particular for active matrix displays devoid of inverted domains having a high rate of voltage maintenance and good stability at low temperatures, is based on compounds with fluorinated terminal and side groups. The composition contains between about 8 and 70% by weight of one or more compounds selected from group (1), in which R1 denotes a straight chain alkyl group having 2 to 5 carbon atoms; E1 denotes (a), (b) or (c); L denotes H or F; and Q denotes OCF2, OCFH, OCFC1, CF2 or a single bond; about 8 to 60% by weight of one or more compounds selected from group (2), in which R2 denotes a straight chain alkyl group having 2 to 5 carbon atoms; E2 denotes (d), (e) or (f); and each L denotes H or F; and/or about 8 to 40% by weight of one or more compounds selected from group (3), wherein R3 denotes a straight chain alkyl group having 2 to 5 carbon atoms; E3 denotes (a), (g) or (h); and Q and L have the above definition, provided that both L denote F when E3 denotes trans-1,4-cyclohexylene. |
