Abstract

The present invention relates to a colored photosensitive resin composition capable of forming a cured film that does not generate uneven wrinkles on its surface, to thereby minimize spots on the display screen that may be generated by a defect in the gap between the upper and lower plates during their assembly, with the formation of an excellent step difference and a pattern in a high resolution; and to a light shielding spacer produced therefrom and used for a liquid crystal display, an organic EL display, or the like.
