Touch screen, manufacturing method thereof, and display device

A manufacturing method of a touch screen, comprising:

• dividing the touch screen into a plurality of mutually independent touch detection regions;
• sequentially forming a plurality of strip transparent electrodes arranged in a first layer along a first direction and extending along a second direction in each of the touch detection regions, and forming two strip ground electrodes, extending along the second direction, arranged in the first layer along the first direction at two edges parallel to the second direction of each of the touch detection region, respectively;
• wherein the second direction is intersected with the first direction;
• and
• forming a plurality of mesh electrodes arranged in a second layer along the second direction and extending along the first direction in the touch detection regions, wherein the strip transparent electrodes and the mesh electrodes are insulated from each other, and the second layer is arranged on the first layer;
• forming a plurality of strip redundant electrodes each located between every two adjacent strip transparent electrodes;
• wherein the plurality of strip redundant electrodes are electrically connected with the plurality of mesh electrodes in a one-to-one corresponding manner;
• wherein projections of the strip transparent electrodes, the strip redundant electrodes, and the two strip ground electrodes on the touch detection region are overlapped with a projection of the mesh electrodes on the touch detection region.
