Curable composition, cured product, color filter, solid-state imaging element, and image display device

A curable composition comprising:

• a block copolymer including a block A which has a constitutional unit having an ethylenically unsaturated group in a side chain;
• a pigment;
• and
• a photopolymerization initiator,
• wherein a content of a polymerizable compound is 15 mass % or less with respect to a total solid content of the curable composition,
• wherein the constitutional unit having an ethylenically unsaturated group in a side chain in the block A includes a constitutional unit represented by Formula (1),
• wherein the block copolymer further includes a block B which has a constitutional unit having a steric repulsive group in a side chain, and
• wherein the steric repulsive group is a group having 20 carbon atoms to 200 carbon atoms,
• in Formula (1), R1 represents a hydrogen atom, a halogen atom, or an alkyl group, X1 and X2 each independently represent a single bond or a divalent linking group, L1 represents a polyether chain, a polyester chain, a polyamide chain, a polyimide chain, a polyimine chain, a polyurethane chain, or a resin chain in which two or more of these resin chains are combined, and Z1 represents an ethylenically unsaturated group.
