As shown in FIG. 21, a twelfth embodiment of the present invention provides a touch device 500. versus The first embodiment is different in that the touch device 500 further includes a cover plate 510 and an adhesive layer 520. The cover plate 510 is disposed opposite to the substrate 110. In addition, the decorative layer 121 of the present embodiment is preferably disposed on the cover plate 510, and the adhesive layer 520 is disposed between the cover plate 510 and the substrate 110 for bonding the cover plate 510 provided with the decorative layer 121 and provided with The substrate 110 of the touch element 150. The adhesive layer 520 may comprise an optical clear adhesive (OCA), a pressure sensitive adhesive (PSA) or other suitable bonding material. It should be noted that the design of the cover plate 510 and the substrate 110 on which the touch element 150 is formed may also be applied to the structure of other embodiments of the present invention as needed.

In summary, the touch device of the present invention utilizes the insulating layer and the protective layer of the bonding region. The first opening or the second opening is respectively disposed, and the first opening and the second opening which are at least partially covered and different in size are mutually matched to expose the respective lines in the joint area, and at the same time, the joint area is protected. The wire reduces the overall thickness of the insulating layer and the protective layer of the bonding region, thereby achieving the purpose of improving product reliability and improving the bonding effect of external components.
