The present invention relates to a positive-type photosensitive resin composition and a cured film prepared therefrom. The composition comprises a photoactive compound of a polymer, and/or a photoactive compound of a monomer, containing a repeat unit having a specific structure. Thus, the exposed portion (i.e., the portion exposed to light) is increased by the interaction between the binder resin (i.e., siloxane copolymer) and the photoactive compound, which increases the solubility in a developer, whereby the sensitivity can be enhanced. In addition, it is possible to form a cured film capable of achieving a high edge angle of a pattern by way of employing the photoactive compound in a proper amount.
