Liquid crystal display device

A liquid crystal display device 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 includes a liquid crystal composition which contains at least one compound represented by general formula (I),
• (in the formula, R31 represents an alkyl group having 1 to 10 carbon atoms, an alkoxy group, or an alkenyl group or alkenyloxy group having 2 to 10 carbon atoms, M31 to M33 each independently represent a trans-1,4-cyclohexylene group or a 1,4-phenylene group, one or two —CH2— in the trans-1,4-cyclohexylene group may be substituted by —O— so that oxygen atoms are not directly adjacent to each other, one or two hydrogen atoms in the phenylene group may be substituted by fluorine atoms, X31 and X32 each independently represent a hydrogen atom or a fluorine atom, Z31 represents a fluorine atom, a trifluoromethoxy group, or a trifluoromethyl group, n31 and n32 each independently represent 0, 1, or 2, n31+n32 represents 0, 1, or 2, and when a plurality of each of M31 and M33 are present, each may be the same or different), and at least one compound selected from the group consisting of compounds represented by general formula (II-a) to general formula (II-e),
• (in the formulae, R21 to R30 each independently represent an alkyl group having 1 to 10 carbon atoms or an alkenyl group having 2 to 10 carbon atoms, and X21 represents a hydrogen atom or a fluorine atom), and
• the RGB three-color pixel portions include, as colorants, a diketopyrrolopyrrole pigment and/or anionic red organic dye in a R pixel portion, at least one selected from the group consisting of a halogenated copper phthalocyanine pigment, a phthalocyanine green dye, and a mixture of a phthalocyanine blue dye and an azo yellow organic dye in a G pixel portion, and a s-type copper phthalocyanine pigment and/or cationic blue organic dye in a B pixel portion.
