Abstract

The present invention provides a curable composition including a pigment, a compound A, a photopolymerization initiator, a curable compound, and a resin, in which a content of the compound A in a total solid content of the curable composition is 1 to 15 mass %. The compound A is a compound including each of a coloring agent partial structure and an acid group or a basic group in the same constitutional unit a and having two or more constitutional units a in one molecule. The present invention further provides a film formed of the curable composition, a color filter, a method for manufacturing a color filter, a solid-state imaging element, and an image display device.
