PROBLEM TO BE SOLVED: To provide a plastic substrate for a display element, the substrate having excellent heat resistance and transparency. SOLUTION: The plastic substrate for a display element contains as a structural component, epoxy resin which is a compound (a) having two or more epoxy groups and which has≥85% purity calculated from oxirane oxygen concentration (measured oxirane oxygen concentration/proportion of oxirane oxygen in the structural formula×100). The compound (a) having two or more epoxy groups is preferably an alicyclic epoxy resin or a hydrogenated biphenyl alicyclic epoxy resin, and the resin is preferably cured with a cationic curative system catalyst.
