Abstract: The present invention relates to a positive photosensitive resin composition and a cured film manufactured therefrom. The positive photosensitive resin composition of the present invention comprises (1) a copolymer including (1-1) a constituent unit derived from carboxyl-containing unsaturated monomer, (1-2) a constituent unit derived from unsaturated monomer including at least one epoxy group, and (1-3) a constituent unit derived from divinyl monomer including acetal backbone; (2) a quinonediazide based photoactive compound; and (3) a photoacid generator. The positive photosensitive resin compound of the present invention has excellent sensitivity and a high retention rate after development and post-cure, and provides a high pattern formation, so as to be useful in manufacturing an insulator film for a liquid crystal display device.
