A fluorene-based hyperbranched polymer resin is provided to have low viscosity and good stability, to be superior in compatability with other composition and solubility, and to be usable for a photosensitive resin composition. A fluorene-based hyperbranched polymer resin includes (a) a compound comprising a fluorene group and having at least two epoxy groups, (b) a compound having at least two acid groups, and (c) a compound having only one functional group capable of reacting with a terminal group of synthesized polymer, wherein both the epoxy groups and the acid groups are not two. The compound of (a) comprising a fluorene group and having at least two epoxy groups is a diepoxy compound comprising a fluorene group. |
