Liquid crystal composition and liquid crystal display device

A liquid crystal composition comprising:

• at least two compounds represented by general formula (i):
• where in the formula, and Ri1 and Ri2 each independently represent a fluorine atom, a chlorine atom, a cyano group or an alkyl group having 1 to 12 carbon atoms, one —CH2— group or two or more non-adjacent —CH2— groups in the alkyl group are each independently optionally replaced with —CH═CH—, —C≡C—, —O—, —CO—, —COO—, or OCO—, one or two or more hydrogen atoms present in each of and Ri1 and Ri2 are each independently optionally replaced with a fluorine atom, provided that either or Ri1 and Ri2, but not both, optionally represents a substituent selected from a fluorine atom, a chlorine atom, and a cyano group,
• Zi1, Zi2, and Zi3 each independently represent a single bond, —OCH2—, —CH2O—, —C2H4—, —C4H8—, —COO—, —OCO—, —CH═CH—, —CF═CF—, —CF2O—, —OCF2—, —CF2CF2—, or —C≡C—,
• Ai1, Ai2, Ai3, Ai4, and Ai5 each independently represent a1,4-cyclohexylene group, a 1,4-phenylene group, a naphthalene-1,4-diyl group, or a naphthalene-2,6-diyl group, one or two or more hydrogen atoms in Ai1, Ai2, Ai3, Ai4 and Ai5 are each independently optionally replaced with a halogen atom or a cyano group, one or more non-adjacent —CH═ groups in Ai1, Ai2, Ai3, Ai4 and Ai5 are optionally replaced with —N═, Xi1 and Xi2 each independently represent a hydrogen atom or a fluorine atom, and
• mi1, mi2, and mi3 each independently represent 0 or 1, provided that mi1+mi2+mi3 is 0 or 1;
• and
• at least one compound represented by general formulae (C1c), and at least one compound represented by general formulae (C2d):
• where in the formulae, Rf and Rg each independently represent a linear alkyl group having 1 to 7 carbon atoms, a linear 1-alkenyl group having 2 to 7 carbon atoms, a linear 3-alkenyl group having 4 to 7 carbon atoms, a linear alkoxy group having 1 to 3 carbon atoms, or a linear alkyl group that has 1 to 5 carbon atoms and that has an end substituted with an alkoxy group having 1 to 3 carbon atoms, wherein at least one of Rf and Rg represents a linear alkyl group having 1 to 7 carbon atoms, a linear 1-alkenyl group having 2 to 7 carbon atoms, or a linear 3-alkenyl group having 4 to 7 carbon atoms,
• rings G2, H2 and 12 each independently represent a trans-1,4-cyclohexylene group, a trans-decahydronaphthalene-trans-2,6-diyl group, a 1,4-phenylene group optionally substituted with one or two fluorine atoms or a methyl group, a naphthalene-2,6-diyl group optionally substituted with one or more fluorine atoms, or a tetrahydronaphthalene-2,6-diyl group optionally substituted with one or two fluorine atoms,
• wherein when ring G2 represent aromatic rings, a 1-alkenyl group and an alkoxy group are excluded from Rf, and when ring H2 represent aromatic rings, a 1-alkenyl group and an alkoxy group are excluded from Rg,
• the total content of the compound according to general formulae (C1c) and the general formulae (C2d) is 2% or more and 60% or less with respect to all compounds in the liquid crystal composition, and
• the liquid crystal composition has a refractive index anisotropy of 0.179 or more.
