A radiation-sensitive resin composition is provided to obtain a shape and a film thickness of a spacer which is enough to exposure amount of 1,500 J/m^2 or less and has a sufficient process margin. A radiation-sensitive resin composition comprises (A) a copolymer of (a1) an ethylenically unsaturated carboxylic acid and/or an ethylenically unsaturated carboxylic anhydride, and (a2) other ethylenically unsaturated compound, (B) a polymerizable compound containing as main components, (b1) tri- or more functional (meth)acrylic acid esters and (b2) an ethylenically unsaturated compound other than (b1), and (C) a radiation-sensitive polymerization initiator. The method for forming a spacer for a LCD panel comprises the processes of: (a) forming a film of the above radiation-sensitive resin composition on a substrate, (b) exposing at least a part of the film, (c) developing the film after exposure, and (d) heating the film after development. |
