Abstract: The present invention relates to a colored photosensitive resin composition that prevents the generation of uneven wrinkles when a cured film is formed, to thereby prevent spots that may be generated on the edges of a display upon the formation thereof, and has a short development time. Accordingly, the colored photosensitive resin composition can be advantageously used as a material for forming a protective film, an interlayer insulating film, a light shielding spacer such as a black column spacer, and the like to be employed in various electronic parts inclusive of a liquid crystal display (LCD) panel and an organic light emitting diode (OLED) display panel.
