Liquid crystal display device

A liquid crystal display apparatus comprising a first substrate, a second substrate, a liquid crystal composition layer held 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 is composed of a liquid crystal composition including one or more compounds represented by General Formula (LC1), the amount of the one or more compounds being more than 90% by mass of the total amount of liquid crystal compounds having a dielectric anisotropy of 2 or more, the liquid crystal compounds constituting the liquid crystal composition,
• (where R1 represents an alkyl group having 1 to 15 carbon atoms;
• one or more CH2 groups of the alkyl group may be replaced by —O—, —CH═CH—, —CO—, —OCO—, —COO—, —C≡C—, —CF2O—, or —OCF2— in such a manner that an oxygen atom is not directly adjacent to another oxygen atom;
• one or more hydrogen atoms of the alkyl group may optionally be replaced by a halogen;
• A1 each independently represents any one of the following structures:
• (in these structures, one or more CH2 groups of the cyclohexane ring may be replaced by an oxygen atom, one or more CH groups of the benzene ring may be replaced by a nitrogen atom, and one or more hydrogen atoms may be replaced by Cl, F, CF3, or OCF3);
• X1 and X2 each independently represent H, Cl, F, CF3, or OCF3;
• Y represents Cl, F, CF3, or OCF3;
• Z1 represents a single bond, —CH═CH—, —C≡C—, —CH2CH2—, —(CH2)4—, —OCH2—, —CH2O—, —OCF2—, or —CF2O—;
• and m1 is an integer of 1 to 3, and
• wherein the RGB three-color pixel portions include, as a coloring material, a pigment having a water-soluble content of 0% by mass or more and 1.5% by mass or less and/or a specific electrical conductivity of 10 μS/cm or more and 150 μS/cm or less.
