Abstract
A light control sheet includes an organic polymer layer that partitions voids, and a liquid crystal composition that contains a non-polymerizable liquid crystal compound and fills the voids. The light control sheet changes the transmittance to visible light by driving the non-polymerizable liquid crystal compound. The liquid crystal composition contains adipate as a non-polymerizable viscosity-reducing agent, and the weight of the non-polymerizable viscosity-reducing agent relative to the weight of the non-polymerizable liquid crystal compound is 1% or more.
