Provided are a liquid crystal composition including at least one or more compounds represented by General Formula (i) and at least one or more compounds represented by General Formula (M-1), in which the dielectric constant anisotropy at 25° C. is larger than 0 and 5 or less; and a liquid crystal display element using this composition. The liquid crystal composition has a positive Δ∈, can have the electrical capacity of the liquid crystal layer (CLC) reduced to a low level, can be driven at a voltage that is practically sufficiently low, and satisfies at least any one of the requirements of maintaining a liquid crystal phase over a wider temperature range, low viscosity, satisfactory solubility at low temperature, high specific resistance or voltage retention rate, and stability to heat or light; and provide an excellent liquid crystal display element. |

1. A liquid crystal composition comprising:
at least one or more compounds represented by General Formula (i):(wherein in General Formula (i), Ri1 and Ri2 each independently represent an alkyl group having 1 to 10 carbon atoms, an alkenyl group having 2 to 10 carbon atoms, or an alkoxy group having 1 to 10 carbon atoms; and at least any one of Ri1 or Ri2 is an alkenyl group), and
at least one or more compounds represented by General Formula (M-1):(wherein in General Formula (M-1), XM12, XM13, XM14, XM15, XM16, and XM17 each independently represent a hydrogen atom or a fluorine atom;
rings A each independently represent a group selected from the group consisting of: (a) a 1,4-cyclohexylene group (one —CH2— moiety or at least two non-adjacent —CH2— moieties present in this group may be substituted by —O—), and (b) a 1,4-phenylene group (one —CH═ moiety or at least two non-adjacent —CH═ moieties present in this group may be substituted by —N═), while the group (a) and the group (b) may be each independently substituted with a cyano group, a fluorine atom, or a chlorine atom; RM1 represents an alkyl group having 1 to 10 carbon atoms, an alkenyl group having 2 to 10 carbon atoms, or an alkoxy group having 1 to 10 carbon atoms; YM11 represents an alkyl group having 1 to 10 carbon atoms, an alkenyl group having 2 to 10 carbon atoms, an alkoxy group having 1 to 10 carbon atoms, a hydrogen atom, a fluorine atom, a cyano group, —CF3, or —OCF3; and n represents an integer from 0 to 2), wherein the dielectric constant anisotropy at 25° C. is larger than 0 and 5 or less. |
