The inventor finds that, as shown in fig. 2, the array substrate of the display device in the prior art includes a touch electrode 21 located in a display area and an electrode trace 22 located in a frame area, where the electrode trace 22 is a metal trace, usually a silver paste, and since the silver paste is opaque, for the sake of beauty, the cover plate of the display device is covered by applying ink on the cover plate, the ink forms the frame area, and the metal trace is located under the frame area, so that the metal trace is not visible. However, no matter what method is adopted in the prior art, the frame is too narrow or existent. With the development of display devices, the display devices have become more demanding for users without a frame.
Accordingly, the present invention provides an array substrate, including:
the display device comprises a substrate, a first display and a second display, wherein the substrate comprises a first area for displaying and a second area for arranging routing, and the second area surrounds the first area;

The touch display panel provided by the invention comprises an array substrate and a color film substrate, wherein the array substrate comprises a substrate, a touch electrode positioned on the substrate and an electrode wire connected with the touch electrode, and the electrode wire is made of nano silver.
