Abstract: Provided are a phosphor-containing capable of suppressing deterioration of phosphors and can be manufactured with high efficiency and a backlight unit. Specifically, provided is a phosphor-containing film, including a first substrate film; and a phosphor-containing layer at which a plurality of regions containing phosphors, which, if exposed to oxygen, deteriorate by reacting with the oxygen, are discretely disposed on the first substrate film, and at which a resin layer having an impermeability to oxygen is disposed between the discretely disposed regions containing phosphors, in which a width S of the resin layer between the regions containing phosphors is 0.01≤S

Abstract: A molding device produces a porous film from a molding material which is an emulsion. In a case where a volume of a dispersed phase is X1 and a volume of a continuous phase is X2, the molding material has a value of X1/(X1+X2) within a range of 0.5 or more and 0.9 or less. In the molding material, a specific gravity of the dispersed phase is greater than a specific gravity of the continuous phase. The molding material includes a water phase containing a curable compound as the continuous phase, and forms a liquid film on a support. Thereafter, the curable compound in the liquid film is cured. After curing, the dispersed phase is removed.

Abstract: A molded body is produced from a molding material including a continuous phase and a dispersed phase by a three-dimensionalization step, a curing step, and a peeling step. The continuous phase of the molding material is a water phase containing a curable compound. In the three-dimensionalization step, the molding material is placed in a container. In the curing step, the curable compound is cured to form a cured product after the three-dimensionalization step. In the peeling step, the container and the cured product are separated after the curing step. In the dispersed phase removal step, the dispersed phase of the cured product is removed after the curing step.
