An object of the present invention is to provide a cured film which is excellent in transparency or heat resistance required for a protective film and does not have a switching threshold deviation due to the specific electrical characteristics of a liquid crystal display device, that is, does not adversely affect display quality, A composition for providing the cured film, and a color filter, a liquid crystal display element, and a touch panel device including the cured film. The problem is solved by a thermosetting composition and a cured film obtained therefrom. The thermosetting composition is a composition containing a polyester amidate and an epoxy compound, and the polyester amidate It is a reactant containing raw materials of tetracarboxylic dianhydride, diamine, and polyhydroxy compound, and the dielectric loss tangent at 20 Hz of the cured film obtained from the composition is 0.007 or less. |
