Abstract:
1. A circuit connecting method comprising the steps of: (a) preparing a first circuit member having first circuit electrodes formed on a main surface of a first boards; (b) preparing a second circuit member having second circuit electrodes formed on a main surface of a second board, wherein an insulating layer is provided on first sections of the second circuit electrodes other than second sections that are connected to the first circuit electrodes; and (c) positioning an anisotropic conductive film so that part of the anisotropic conductive film overlaps part of the insulating layer, and bonding the first circuit member and the second circuit member via the anisotropic conductive film to form a circuit connection forming an electrical connection between the first circuit electrodes and the second circuit electrodes, wherein a thickness of the anisotropic conductive film prior to bonding is no greater than the total of the height of the first circuit electrodes and the height of the second circuit electrodes.
