Abstract
An object of the present invention is to provide: a curable composition comprising a fluorescent particle containing a perovskite compound, wherein the maintenance rate of the quantum yield after curing the curable composition by photoirradiation to form a cured film relative to the quantum yield before forming the cured film is high; a film formed by curing the curable composition; and a laminated body and a display apparatus comprising the film. Provided are: a curable composition comprising a fluorescent particle (A) containing a perovskite compound, a photopolymerizable compound (B), and a photopolymerization initiator (C), wherein the expression: 5.0×10≤(Ab× M)/M≤1.0 is satisfied, wherein M[% by mass] represents the content of the fluorescent particle (A) and M[% by mass] represents the content of the photopolymerization initiator (C) in 100% by mass of the solid content of the curable composition, and Abrepresents the absorbance of the photopolymerization initiator (C) at a wavelength of 365 nm and at a concentration of 1 mg/100 mL; a film formed by curing the curable composition; and a laminated body and a display apparatus comprising the film.
