Provided is a composite liquid crystal composition which contains a liquid crystal compound and a polymerizable compound, has sufficiently high Δn, further has high photostability, and can constitute a liquid crystal device capable of being driven at a low voltage. The composite liquid crystal composition includes, as the liquid crystal compound, a compound having a biphenyl skeleton and two or more compounds represented by Formula (I-a), in which the content of the compound having a biphenyl skeleton is 20% by mass or less of the liquid crystal compounds, and the content of the compound represented by Formula (I-a) in which C1 represents a 1, 4-cyclohexylene group and n1 is not 0 is 45% by mass or more of the liquid crystal compounds; and as the polymerizable compound, one or more compounds selected from the compounds represented by Formulas (II-a1) and (II-a2) and a compound represented by (II-b), in which the total content of the liquid crystal compounds is 65% to 85% by mass, and the total content of the polymerizable compounds is 15% to 35% by mass.
