Abstract: The present invention relates to a method for preparing a column spacer, and is characterized in using a mask including first, second, and third patterns having different light transmittance. In addition, according to the method for preparing a column spacer of the present invention, a taper angle between a matrix part and a spacer part may increase during manufacturing a column spacer in which the matrix part and the spacer part are continuously connected, and critical dimension of the spacer part may decrease. Therefore, a column spacer with fine patterns may be simply and efficiently manufactured.

Abstract: 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.

Abstract: Disclosed herein are a photosensitive resin composition and a cured film prepared therefrom. By comprising a copolymer (A) and a photopolymerizable compound (B) in specific amounts, a photosensitive resin composition may form a cured film having pattern developability with high resolution and good elasticity recovery rate. The composition may be effectively used for the formation of a cured film, particularly a spacer of a display device such as a liquid crystal display and an organic electroluminescence device.
