Claim:
1. A liquid crystal display device comprising a first substrate, a second substrate, a liquid crystal composition layer sandwiched between the first substrate and the second substrate, a color filter constituted by 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 containing: 30% to 50% of a compound represented by general formula (I), in the formula (I), R 5% to 20% of a compound represented by general formula (II-1), in the formula (II-1), R 25% to 45% of a compound represented by general formula (II-2), in the formula (II-2), R 5% to 20% of a compound represented by general formula (III), wherein in the formula, R wherein the RGB three color pixel portions contain, as coloring materials, a diketopyrrolopyrrole pigment and/or an anionic red organic dye in an R pixel portion, a halogenated copper phthalocyanine pigment in a G pixel portion, and an ε-type copper phthalocyanine pigment and/or a cationic blue organic dye in a B pixel portion, a total content of the compounds represented by general formula (I), general formula (II-1), general formula (II-2), and general formula (III) is 90% to 100% of the liquid crystal composition.
