A light control layer includes an ionizing radiation-curable resin layer having voids and a liquid crystal composition filled in the voids. An acrylic compound having 3 or more functional groups and a double bond equivalent weight of 150 g/eq or less is a first acrylic compound. A monofunctional alkyl acrylate containing a saturated alkyl group is a second acrylic compound. An acrylic compound having 1 to 3 functional groups and a polyethylene oxide chain and a double bond equivalent weight of 300 g/eq to 700 g/eq is a third acrylic compound is a third acrylic compound. A content of the first acrylic compound is 5 mass % to 40 mass %. A content of the second acrylic compound is 55 mass % to 80 mass %. A content of the third acrylic compound is 5 mass % to 20 mass %.
