If the transparent conductor layer covers the first conductor electrode 132 in a large form and the plurality of first transparent conductor island patterns 134 are disposed on the first conductor electrode 132 with the adapter structures 130a and 130b of the present embodiment. Compare with each other. The embodiment of the present invention can reduce the area of the first transparent conductor island pattern 134 on the first conductor electrode 132, but greatly increase the contact area between the insulating layer 138 and the first transparent conductor island pattern 134, and the insulating layer 138 is in direct contact with the first conductor electrode 132, so that the insulating layer 138 has good adhesion to the first transparent conductor island pattern 134. Therefore, during the subsequent tear film process (such as the process of removing the peelable glue or removing the protective film temporarily used in the process), the insulating layer 138 and the first transparent conductor island pattern in the transfer structure 130a, 130b are used. There is good adhesion between the 134, so that the insulating layer 138 is not affected by the external force and is peeled off by the first transparent conductor island pattern 134, so that the adapter structures 130a, 130b can maintain a good structure.

On the other hand, since the first transparent conductor island pattern 134 is located under the first opening 138a of the insulating layer 138, the first transparent conductor island pattern 134 can serve as a protective pad of the first conductor electrode 132. For example, the etching process for forming the first opening 138a may over-etch the insulating layer 138 and etch to the lower film layer exposed through the first opening 138a. At this time, the first transparent conductor island pattern 134 can be used as the first The barrier layer of the conductor electrode 132 prevents the first conductor electrode 132 from being damaged by direct bombardment by plasma or the like, so that the first conductor electrode 132 can maintain good electrical characteristics. Therefore, the transfer structure 130a, 130b can have a good transfer function, so that the touch panel and the touch display panel using the touch panel have better good performance. Rate with good touch function.

In summary, in the touch panel and the touch display panel of the present invention, the transfer structure has a plurality of first transparent conductor island patterns disposed on the first conductor electrode and below the first opening of the insulating layer. The insulating layer and the first transparent conductor island are formed because the insulating layer fills the gap between the first conductor electrodes and contacts the first conductor electrode and covers the side and part of the top surface of each of the first transparent conductor island patterns. There is good adhesion between the patterns. In this way, in the tearing film step of the rear stage, peeling of the insulating layer in the transfer structure from the first transparent conductor island pattern can be avoided, so that the transfer structure has a good transfer function. In addition, the first transparent conductor island pattern serves as a protective pad for the first conductor electrode to prevent foreign matter from being broken through the first opening, so that the first conductor electrode has good characteristics. Therefore, the touch panel of the present invention and the touch display panel using the touch panel have better yield and good touch function.
