Abstract: A light control sheet is reversibly changeable between transparent and opaque in response to a change in alignment of a liquid crystal compound. The light control sheet includes a light control layer including a polymer resin layer in which voids are dispersed, and a liquid crystal composition containing the liquid crystal compound. The liquid crystal composition is filling the voids. In the light control layer, a percentage of a volume of the liquid crystal composition relative to a total volume of the polymer resin layer and the liquid crystal composition is 40% or greater and 60% or less. Avoid diameter of the voids is 2 μm or less.
