Abstract: A flexible circuit board includes a plurality of first wires that have a first connection area and a first insulating layer that covers the first wires such that the first connection area is exposed. A printed circuit board includes a plurality of second wires that have a second connection area, a second insulating layer that covers the second wires such that the second connection area is exposed, and a plurality of island conductors adjacent to the second wires across a gap. The second connection area is covered with an anisotropic conductive layer. Each of the second wires in the second connection area at least partially faces a corresponding one of the wires in the first connection area across the anisotropic conductive layer. The plurality of island conductors include an island conductor that is in contact with the anisotropic conductive layer and partially exposed from the anisotropic conductive layer.
