Abstract: The present invention relates to a colored photosensitive resin composition and to a light shielding spacer produced therefrom. The colored photosensitive resin composition comprises epoxy groups and double bonds in a specific molar ratio and an oxime ester fluorene-based photopolymerization initiator in a smaller amount than a conventional oxime ester-based photopolymerization initiator, so that it has excellent photo-curing characteristics. As a result, it is possible to improve the high sensitivity characteristics such as resolution and step difference even with a small amount of light. Specifically, since the curing characteristics of the film surface is improved, it is to possible to reduce the generation of outgassing, which is a contamination source that may be generated when the film is dried. In addition, the colored photosensitive resin composition is capable of forming a cured film that minimizes the generation of uneven wrinkles on its surface.
