To provide a material which excels in transparency, chemical resistance, and heat resistance, in which a crack is not produced, and which can obtain a cured film with a thickness of 15-200 μm by coating, and to provide a cured film and a display element using the same.
The thermosetting polymer composition includes: a copolymer (A) consisting of a radically polymerizable monomer (a1) which has oxetanyl, a radically polymerizable monomer (a2) which has an alicyclic structure, and a (meth)acrylic acid ester (a3) which has a specific alkyl; and a copolymer (B) consisting of a radically polymerizable monomer(b1) which has a carboxylic acid structure or an acid anhydride structure and other radically polymerizable monomers (b2), and is used, whereby the cured film by the thermosetting of the composition is formed, and the display element which has the cured film is provided.
