Abstract
Disclosed herein are a black photosensitive resin composition and a black column spacer prepared therefrom. The black photosensitive resin composition may form a cured film exhibiting good adhesion to a substrate, good height difference property, good surface roughness and high light shielding property (optical density), and may be effectively used for the formation of a cured film, particularly a black column spacer, of a liquid crystal display (LCD) or an organic light-emitting diode (OLED) display.
