Abstract
The embodiment of the present invention discloses a touch screen, its manufacturing method and a display device. The method comprise the following steps: first, forming patterns of shielding layer on a substrate; then forming patterns of bridging layer and peripheral traces on the shielding layer by a single patterning process; thereafter, forming patterns of insulating layer on the peripheral traces; and finally, forming patterns of touch control electrode layer. In the present invention, the patterning of the bridging layer and peripheral traces can be achieved by a single patterning process using a mask plate, which reduces the number of patterning processes in the manufacturing process and improves the manufacturing efficiency of the touch screen thereby reducing the cost of production.
