The present application relates to a compound and an organic light emitting device comprising the same.

The present application relates to a compound and an organic light emitting device comprising the same.

Disclosed herein is a colored photosensitive resin composition including a copolymer, an epoxy resin compound or a compound derived therefrom, a polymerizable compound, a photoinitiator, and a colorant, wherein the photoinitiator includes an oxime compound and a triazine compound. The composition, when formed into a cured film, may facilitate the fabrication of necessary height difference and satisfy the requirements of sensitivity and an exposure margin for light shielding spacers, and, thus, is useful as a material for manufacturing a light shielding spacer such as a black column spacer used in various electronic parts including the panels of an LCD and an OLED display.
