Description

Technical field [0001] The present invention relates to a photosensitive polymer and a photosensitive composition containing the photosensitive polymer. The present invention relates to a cured film formed of the photosensitive composition, a color filter, an insulating film, a protective film, and the like using the cured film. Furthermore, this invention relates to the manufacturing method of the said photosensitive polymer. Background technique [0002] In the usual manufacturing steps of elements such as display elements, chemical treatments or high-temperature heat treatments are applied to their surfaces. In order to prevent deterioration, damage, and deterioration caused by the treatment, a protective film is provided on the surface of the element. The protective film requires heat resistance, chemical resistance, adhesion to the substrate, transparency, flatness, etc., as well as good resolution and residual film rate. [0003] In order to form a protective film, it is r...
