Abstract:
A liquid crystal composition which comprises as a first component at least one compound selected from the group of compounds represented by the formula (I) and as a second component at least one compound selected from the group of compounds represented by the formula (II), wherein the content of the first component is 30 to 95% by weight and the content of the second component is 5 to 70% by weight, based on the total weight of the composition wherein R1 and R3 are independently an alkyl of 1 to 10 carbon atoms and any â€”CH2â€” in the alkyl may be replaced by â€”Oâ€” or â€”CH&boxH;CHâ€”; R2 is an alkyl of 1 to 10 carbon atoms, â€”F or â€”Cl; X1, X2, X3, X4, X5, X6, X7, X8 and X10 are independently â€”F or â€”H, wherein at least one of X1, X2 and X3 is â€”F; X9 is â€”F, â€”Cl, â€”CF3, â€”OCF3 or â€”OCF2H; A1 is 1,4-cyclohexylene, or 1,4-phenylene in which any â€”H may be replaced by â€”F; A2 is 1,4-cyclohexylene, pyrimidine-2,5-diyl or 1,4-phenylene in which any â€”H may be replaced by â€”F; Z1 and Z3 are independently a single bond, â€”(CH2)2â€” or â€”(CH2)4â€”; Z2 is a single bond or â€”CF2Oâ€”; and Z4 is a single bond, â€”COOâ€” or â€”CF2Oâ€”.
