OG Complex Work Unit Chemistry
in the general formula (iv),
Riv1 and Riv2 each independently represent an alkyl group having 1 to 20 carbon atoms,
in the alkyl group, one or two or more —CH2— may each independently be substituted with —O— and/or —CO—,
in the alkyl group, one or two or more —CH2—CH2— may each independently be substituted with —CH═CH— and/or —C≡C—, and
in the alkyl group, one or two or more hydrogen atoms may each independently be substituted with a halogen atom,
with the proviso that no direct bond between an oxygen atom and an oxygen atom is formed; and
one or two or more dye compounds,
a total content of the compounds represented by the structural formulas (i-1.1) to (i-1.8) relative to 100 mass % of the dye compound-containing liquid crystal composition is 10 to 30 mass %,
a total content of the compounds represented by the structural formulas (ii-1.1) to (ii-1.4) relative to 100 mass % of the dye compound-containing liquid crystal composition is 10 to 20 mass %,
a total content of the compounds represented by the general formula (iv) relative to 100 mass % of the dye compound-containing liquid crystal composition is 12 mass % or more.
