The photosensitive resin composition introduces a siloxane polymer containing a fluorine atom which has strong water-repellency into a composition including a common siloxane polymer and an epoxy compound, and fluorine groups may be present in the whole region of the cured film so that the water-repellency due to a fluorine component may be maintained even after removing the surface of the cured film is removed via a dry etching process. As a result, the resistance (chemical resistance) to chemicals used in a post-processing can be maximizes to provide a cured film having excellent stability.
