ABSTRACT:
A photosensitive resin composition for forming column spacers for a liquid crystal display device is provided. The composition includes an alkali-soluble resin, a reactive unsaturated compound, a photoinitiator and a solvent. The alkali-soluble resin includes structural units represented by Formulae 1, 2 and 3, which are described in the specification. A pattern formed using the composition is also provided. The pattern shows improved thickness uniformity, good developability without leaving any residual image, superior solvent resistance and high recovery rate.
