Claim:
1. A liquid crystal composition comprising: a first component comprising one or more fluorobenzene derivatives having a 1-propenyl group represented by general formula (I-1), and one or more fluorobenzene derivatives having a 1-propenyl group represented by general formula (I-2); and one or more liquid crystal compounds having negative Δ∈ with an absolute value of 3 or more as a second component, in the general formula (I-2), R 11 represents an alkyl group having 1 to 5 carbon atoms, an alkoxy group having 1 to 5 carbon atoms, an alkenyl group having 2 to 5 carbon atoms, or an alkenyloxy group having 2 to 5 carbon atoms; Z 11 and Z 12 each represent —CH 2 O—,—or a single bond; Ring A and Ring B each represent a trans-1,4-cyclohexylene group, a 1,4-phenylene group, or a 1,4-cyclohexenylene group; and m and n each independently represent 0 or 1, in the general formula (I-2). R 11 represents an alkyl group having 1 to 5 carbon atoms, an alkoxy group having 1 to 5 carbon atoms, an alkenyl group having 2 to 5 carbon atoms, or an alkenyloxy group having 2 to 5 carbon atoms; Z 11 represents a single bond and Z 12 represents —CH 2 O—, —CF 2 O—, —CH 2 CH 2 —, or a single bond; Ring A and Ring B each independently represent a trans-1,4-cyclohexylene group, a 1,4-phenylene group, or a 1,4-cyclohexenylene group; and m represents 1 and n represents 1, wherein the one or more fluorobenzene derivatives having a 1-propenyl group represented by general formula (I-1) includes a compound wherein m represenis 0 and n represents 1.
