[PROBLEMS] To provide a high sensitivity even when a light source cut from a short wavelength is used, for example, a sufficient spacer shape can be obtained even with an exposure amount of 1,000 J / m 2 or less, elastic recovery, rubbing resistance, and transparency. To provide a radiation-sensitive resin composition capable of forming a spacer for a liquid crystal display element having excellent adhesion to a substrate and heat resistance. The radiation-sensitive resin composition comprises: [A] (a1) at least one selected from the group consisting of an unsaturated carboxylic acid and an unsaturated carboxylic acid anhydride; and (a2) an inert material other than the above (a1). A copolymer of a saturated compound, [B] a polymerizable unsaturated compound, and [C] the following compound No. 1 The specific oxime ester represented by is contained. [Selection figure] None |
