The invention relates to a photosensitive composition, a hardened film, a color filter, a display element, a solid-state shooting element, and a light-emitting diode illuminator. The photosensitive composition contains polyester amic acid, a compound having a polymerizable double bond, a photopolymerization initiator, an epoxy compound, and an epoxy curing agent. In the photosensitive composition,the polyester amic acid is obtained by reacting a tetracarboxylic dianhydride, a diamine, and a polyvalent hydroxy compound as essential raw material components, and the compound having a polymerizable double bond contains two or more polymerizabilities per molecule. A compound having a polymerizable double bond contains more than two polymerizable double bonds having molecular weight of less than 1,000 in each molecule, and a compound having a polymerizable double bond and having a molecular weight of 1,000 or more. The photosensitive composition of the present invention can form a hardenedfilm which is excellent in transparency, heat resistance, solvent resistance, adhesion, flatness, and resolution without requiring an organic solvent having a high polarity.
