Abstract
A liquid crystal composition includes: 20 to 50 wt % of compound (A) 0 to 20 wt % of compound (B) 20 to 50 wt % of compound (C) R3-G3-M1-R4; (C) 1 to 15 wt % of compound (D) and 5 to 15 wt % of compound (E) wherein G1, G2, G3, G4, G5, G6, M1, and M2 are independently phenylene or cyclohexylene; R1, R2, R3, R4, R5, R6, and R7 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 the alkyl group is optionally substituted and can be replaced with at least one fluorine atom; X1, X2, X3, X4, X5, X6, X7, Y1, and Y2 are independently H, F, Cl, CHF3, or OCF3; 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.
