Patent ID: 7215331

Claim:
A touch panel comprising: first and second opposing substrates, each substrate having an extension formed at one side, and each substrate having a dead space area and a viewing area; first and second transparent electrodes formed on surfaces of the first and second substrates facing each other; a first signal transmitting metal electrode connected to the first transparent electrode; a second signal transmitting metal electrode connected to the second transparent electrode; a signal line for applying a signal to each transparent electrode, a conductive sealant for electrically bonding the signal line to the first signal transmitting metal electrode and the second signal transmitting metal electrode in the extension; and an insulating sealant for bonding the first and second substrates to each other, wherein the conductive sealant has a melting point that is below a melting point of the insulating sealant, and wherein the insulating sealant and extension prevent the conductive sealant from flowing into the viewing area when the signal line is bonded to the first signal transmitting metal electrode and the second signal transmitting metal electrode.
