1. A liquid crystal display device comprising a first substrate, a second substrate, a liquid crystal composition layer disposed between the first substrate and the second substrate, a color filter including a black matrix and at least RGB three-color pixel portions, a pixel electrode, and a common electrode, wherein
the liquid crystal composition layer contains a liquid crystal composition containing a compound represented by Formula (I) in an amount of 30 to 50% (where R1 and R2 each independently represent an alkyl group having 1 to 8 carbon atoms, an alkenyl group having 2 to 8 carbon atoms, an alkoxy group having 1 to 8 carbon atoms, or an alkenyloxy group having 2 to 8 carbon atoms; and A represents a 1,4-phenylene group or a trans-1,4-cyclohexylene group), a compound represented by Formula (II-1) in an amount of 5 to 30% (where R3 represents an alkyl group having 1 to 8 carbon atoms, an alkenyl group having 2 to 8 carbon atoms, an alkoxy group having 1 to 8 carbon atoms, or an alkenyloxy group having 2 to 8 carbon atoms; R4 represents an alkyl group having 1 to 8 carbon atoms, an alkenyl group having 4 to 8 carbon atoms, an alkoxy group having 1 to 8 carbon atoms, or an alkenyloxy group having 3 to 8 carbon atoms; and Z3 represents a single bond, —CH═CH—, —C≡C—, —CH2 CH2—, —(CH2)4—, —COO—, —OCO—, —OCH2—, —CH2O—, —OCF2—, or —CF2O—), and a compound represented by Formula (II-2) in an amount of 25 to 45% (where R5 represents an alkyl group having 1 to 8 carbon atoms, an alkenyl group having 2 to 8 carbon atoms, an alkoxy group having 1 to 8 carbon atoms, or an alkenyloxy group having 2 to 8 carbon atoms; R6 represents an alkyl group having 1 to 8 carbon atoms, an alkenyl group having 4 to 8 carbon atoms, an alkoxy group having 1 to 8 carbon atoms, or an alkenyloxy group having 3 to 8 carbon atoms; B represents a 1,4-phenylene group or trans-1,4-cyclohexylene group which is optionally substituted with a fluorine atom, and Z4 represents a single bond, —CH═CH—, —C≡C—, —CH2 CH2—, —(CH2)4—, —COO—, —OCO—, —OCH2—, —CH2O—, —OCF2—, or —CF2O—), and the black matrix contains a colorant that is at least one pigment selected from carbon black, titanium black, and an organic pigment. |
