Zusammenfassung:	To provide a cured film that is excellent in transparency or heat resistance required for a protective film and that the display quality is not adversely affected by not having variations in switching threshold caused by specific electrical characteristics of a liquid crystal display device; a composition for making the cured film, a color filter comprising the cured film, a liquid crystal display element, and a touch panel device. A thermosetting composition and a cured film obtained therefrom, the thermosetting composition being a composition containing a polyester amic acid and an epoxy compound, the polyester amic acid being a reactant containing raw materials of a tetracarboxylic dianhydride, a diamine, and a polyvalent hydroxy compound, and the dielectric loss tangent at 20 Hz of the cured film obtained from the composition is 0.007 or less.
