Abstract:
1. A connection configuration in which rigid substrates are connected via flexible substrates, comprising: a pair of rigid substrates each having a predetermined circuit pattern on a front and a reverse surface thereof, a first flexible substrate attached on the front surfaces of the pair of the rigid substrates so as to electrically connect the circuit patterns provided respectively on the front surfaces, a second flexible substrate attached on the reverse surfaces of the pair of the rigid substrates so as to electrically connect the circuit patterns provided respectively on the reverse surfaces, wherein the first and the second flexible substrate have a gap therebetween smaller than a thickness of the pair of the rigid substrates, wherein the first flexible substrate is attached on the front surfaces adjacent to one side surface of each rigid substrate of the pair of the rigid substrates, the first flexible substrate having a first curved portion in which the first flexible substrate bends from the front surfaces of the rigid substrates toward the reverse surfaces of the rigid substrates and having a second curved portion in which the first flexible substrate bends so as to be substantially parallel with the pair of the rigid substrates. wherein the second flexible substrate is attached on the reverse surfaces adjacent to the side surface of each rigid substrate of the pair of the rigid substrates, the second flexible substrate having a third curved portion in which the second flexible substrate bends from the reverse surfaces of the rigid substrates toward the front surfaces of the rigid substrates and having a fourth curved portion in which the second flexible substrate bends so as to be substantially parallel with the pair of the rigid substrates, and wherein a space substantially determined by the first curved portion, the second curved portion, the third curved portion, the fourth curved portion and the side surface of each of the rigid substrates is filled with a first adhesive.
