Abstract
Provided are a curable composition including a compound represented by Formula (1) or Formula (2), a curable compound, and a solvent; a film formed of the curable composition; a near-infrared cut filter; a solid-state imaging element; an image display device; an infrared sensor; and a camera module. In the formulae, X1 to X5 each independently represent O, S, or a dicyanomethylene group, and R1 to R5 each independently represent a group represented by Formula (R2), and the like, in which at least one of R1 or R2 is the group represented by Formula (R2) and at least one of R3 or R4 is the group represented by Formula (R2).
