A radiation-sensitive resin composition is provided to form a spacer for a liquid crystal display device having excellent adhesion, rubbing resistance and heat resistance even under a low light dose, and showing flexibility, high elastic restorability and excellent developability to an alkaline developer. A radiation-sensitive resin composition comprises: [A] a copolymer of (a1) at least one selected from unsaturated carboxylic acids and anhydrides thereof, (a2) an unsaturated compound represented by the following formula 1, and (a3) at least one unsaturated compound selected from the group consisting of alkyl acrylate, alkyl methacrylate, alicyclic acrylate, alicyclic methacrylate, aryl acrylate, aralkyl acrylate, aryl methacrylate, aralkyl methacrylate, dialkyl dicarboxylate, hydroxyalkyl methacrylate, methacrylate of an unsaturated 5- or 6-membered ring containing one oxygen atom, epoxyalkyl acrylate, epoxyalkyl methacrylate, epoxyalkyl alpha-alkylacrylate, glycidyl ether having an unsaturated bond, vinyl aromatic compounds, dicarbonyl imide derivatives, conjugated dienes, acrylonitrile, methacrylonitrile, acrylamide, methacrylamide, vinyl chloride, vinylidene chloride and vinyl acetate; [B] a polymerizable unsaturated compound; and [C] a radiation-sensitive polymerization initiator. In formula 1, each of R1 and R2 is H or monovalent organic group; R3 is H or methyl; and X is a divalent organic group. |
