Abstract: Provided is a polymer dispersed liquid crystal display device including: a pair of substrates including an electrode on at least one substrate; and a composite layer disposed between the pair of substrates. The composite layer includes a liquid crystal component and a polymer network constituted by a cured product of a photopolymerizable liquid crystal compound, and is in a transparent state when no voltage is applied and in a scattering state when a voltage is applied, and the polymer network has a helical structure with a number of turns of from one to less than eight in the composite layer.
