Method for manufacturing touch panel, touch panel and display device

A touch panel, comprising:

• a substrate;
• a first electrode and a first pin, disposed on the substrate, the first electrode and the first pin being electrically interconnected;
• an insulating layer disposed on the first electrode, the insulating layer being disposed with an opening to expose the first pin;
• a second electrode and a second pin, disposed on the insulating layer, the second electrode and the second pin being electrically interconnected, the first electrode being disposed opposite to the second electrode, the second pin being disposed inside the opening, and the first pin and the second pin being arranged in a zigzag manner,
• wherein the first electrode and the first pin are formed of a first same layer of material and are integrally connected as a one-piece structure and the second electrode and the second pin are formed of a second same layer of material that is spaced from the first same layer of material of the first electrode and the first pin and are integrally connected a one-piece structure;
• and wherein the insulating layer has a portion located in the spacing between the first and second same layers of material, such that the first electrode and the second electrode are respectively located on two opposite sides of the insulating layer and the insulating layer is sandwiched between and in direct contact with the first and second electrodes.
