PHOTOSENSITIVE RESIN COMPOSITION FOR FORMING COLUMN SPACER OF LIQUID CRYSTAL DISPLAY, METHOD FOR FORMING COLUMN SPACER USING THE COMPOSITION, COLUMN SPACER FORMED BY THE METHOD, AND DISPLAY DEVICE COMPRISING THE COLUMN SPACER

摘要

Disclosed is a photosensitive resin composition used to form spacers of a liquid crystal display device. The photosensitive resin composition comprises [A] an alkali- soluble resin, [B] a reactive unsaturated compound, [C] a photopolymerization initiator and [D] a solvent wherein the alkali-soluble resin [A] is a copolymer including structural units represented by Formulae 1 to 3, which are described in the specification. Column spacers formed using the photosensitive resin composition exhibit high compressive displacement, elastic recovery and residual film ratio.
