Patent ID: 8330052

Claim:
A joined structure, comprising: an anisotropic conductive film; a substrate containing a first electrode region formed thereon and having a chamfer part at an edge thereof; and a wiring member, wherein the anisotropic conductive film and the wiring member are joined together with the anisotropic conductive film, wherein one edge of the anisotropic conductive film is placed on the first electrode region of the substrate so that the one edge of the anisotropic conductive film protrudes from the inner edge of the chamfer part of the substrate towards the outer side of the substrate, wherein the wiring member contains a wiring plate formed thereon, where the wiring plate has a resist region in which the wiring plate is covered with a resist layer, and a second electrode region in which the wiring plate is not covered with the resist layer, and the wiring member is placed so that the edge of the resist region at a boundary with the second electrode region comes above the chamfer part of the substrate, and wherein the second electrode region is covered with the anisotropic conductive film.
