Disclosed herein is a colored photosensitive resin composition comprising a copolymer, an epoxy resin compound or a compound derived therefrom, a polymerizable compound, a photoinitiator, and a color former, wherein the photoinitiator comprises a ruthenium compound and a triazine compound . The composition, when formed into a cured film, can help to produce the necessary height difference and meet the sensitivity and exposure margin requirements of the light-shielding spacer, and is therefore suitable for use as a material for making a light-shielding spacer, the light-shielding spacer being Such as black column spacers for a variety of electronic components including LCD and OLED display panels. |
