To provide a spacer composition optimized for the manufacture of a spacer by a low-cost ink jet method and to provide a spacer formed from the composition and a liquid crystal display element equipped with the spacer.
The composition comprises: [A] a copolymer of (a1) an unsaturated carboxylic acid and/or unsaturated carboxylic acid anhydride, (a2) an epoxy group-containing unsaturated compound and (a3) an olefin unsaturated compound except for compounds of (a1) and (a2); [B] a polymerizable compound having an ethylenic unsaturated bond; [C] a radiation sensitive polymerization initiator; and [D] a solvent having ≥180°C boiling point at normal pressure. The spacer is formed from the above composition, and the liquid crystal display element has the above spacer.
