Disclosed is a radiation-sensitive resin composition for spacers, which has high sensitivity and excellent storage stability. Also disclosed are a spacer formed by using such a radiation-sensitive resin composition, a method for forming such a spacer, and a liquid crystal display device comprising such a spacer. Specifically disclosed is a radiation-sensitive resin composition for forming spacers, which contains (A) a resin having, in a side chain, a branched structure and/or an alicyclic structure, an acidic group, and an ethylenically unsaturated group bonded to the main chain through an ester group, (B) a polymerizable unsaturated compound, and (C) a hexaarylbiimidazole compound (C1), an aromatic mercapto compound (C2) and an assistant (C3). |
