Liquid crystal display device

A liquid crystal display device comprising:

• a first substrate;
• a second substrate;
• a liquid crystal layer between the first substrate and the second substrate;
• a color filter;
• a pixel electrode;
• and a common electrode;
• the color filter including a black matrix and at least RGB three-color pixel units,
• wherein the liquid crystal layer is formed of a material containing chiral liquid crystals, the material containing chiral liquid crystals containing a nematic liquid crystal composition and at least one chiral compound, the nematic liquid crystal composition containing at least two achiral liquid crystal compounds, and
• the RGB three-color pixel units contain a halogenated metal phthalocyanine pigment as a coloring material in the G pixel unit, the halogenated metal phthalocyanine pigment containing a metal selected from the group consisting of Al, Si, Sc, Ti, V, Mg, Fe, Co, Ni, Zn, Ga, Ge, Y, Zr, Nb, In, Sn, and Pb as a central metal, wherein in the case where the central metal is trivalent, the central metal is bonded to or oxo- or thio-cross-linked to one halogen atom, hydroxy group, or sulfonate group, and in the case where the central metal is a tetravalent metal, the central metal is bonded to one oxygen atom, two same or different halogen atoms, a hydroxy group, or a sulfonate group,
• wherein the nematic liquid crystal composition has a nematic liquid crystal phase at least in a temperature range of −10° C. to 50° C.
