Abstract:
1. A liquid crystal composition comprising: 20 to 50 wt % of compound (A) 0 to 20 wt % of compound (B) 20 to 50 wt % of compound (C) 1 to 15 wt % of compound (D) and 5 to 15 wt % of compound (E) wherein G 1 , G 2 , G 3 , G 4 , G 5 , G 6 , M 1 , and M 2 are independently phenylene or cyclohexylene; R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , and R 7 are independently a straight-chain or branched-chain alkyl group having 1 to 7 carbon atoms or an alkenyl group having 2 to 7 carbon atoms, where said alkyl group is optionally substituted and can be replaced with at least one fluorine atom; X 1 , X 2 , X 3 , X 4 , X 5 , X 6 , X 7 , Y 1 , and Y 2 are independently selected from the group consisting of H, F, Cl, CF 3 , and OCF 3 ; a and b are independently 0, 1 or 2; c is 0 or 1; d is 0 or 1, but c+d≧1; and e is 0, 1 or 2; and wherein, when G 4 is cyclohexylene, c=1, and d=0, R 6 cannot be CF 3 .
