Abstract

The present invention relates to a colored photosensitive resin composition and to a light shielding spacer prepared therefrom. The colored photosensitive resin composition comprises an oxime ester fluorene-based compound as a photopolymerization initiator in a small amount, which is capable of forming a cured film that is excellent in terms of such properties as sensitivity, elastic recovery rate, resolution, chemical resistance, exudation resistance, voltage holding ratio, and the like. Accordingly, a light shielding spacer prepared therefrom can be advantageously used for a liquid crystal display, an organic EL display, and the like.
