Touch panel and manufacturing method thereof

A manufacturing method of a touch panel, comprising:

• providing a substrate, wherein the substrate has a first surface and a second surface opposite to each other;
• forming a first recess portion on the first surface of the substrate, and defining a display area on the first surface, wherein the first recess portion is located outside the display area;
• forming a first vision opaque layer on the first surface, wherein a part of or all of the first vision opaque layer is filled in the first recess portion;
• forming an electrode layer on the first surface, wherein a part of the electrode layer is located on the display area, and the other part of the electrode layer is located on the first vision opaque layer, and when an object touches or approaches the touch panel, the electrode layer correspondingly generates a touch signal;
• and
• forming a metal material layer on the first surface, wherein the metal material layer is located on the first vision opaque layer and is electrically connected to the electrode layer to transmit the touch signal.
