PROBLEM TO BE SOLVED: To obtain the subject structure not causing the failure of electric conduction and the deterioration in the display quality of the display device without requiring a heating process by joining a lead electrode terminal formed on the liquid crystal substrate of a display element to the joining terminal of a driving circuit substrate through an anisotropic conductive material having a specific composition. SOLUTION: A lead electrode terminal formed on the liquid crystal substrate (for example, a liquid crystal display) of a display element is joined to the joining terminal of a driving circuit substrate through an anisotropic conductive material comprising (A) a cation-polymerizable compound, (B) a photo-cation polymerization initiator, and (C) conductive particles. The driving circuit substrate preferably comprises a flexible printed wiring substrate, etc. The component A is preferably an epoxy resin. Examples of the component B include an aromatic diazonium salt. The component B is preferably added in such an amount as to produce >=0.0001 mole of a cation per mole of the epoxy group. Example of the component C includes the particles of a conductive metal such as gold.
