Abstract
The present invention discloses a touch screen panel and a method for manufacturing the same, and a display device. The method comprises: forming patterns of a bridging layer and a shielding layer on a substrate by one patterning process; then forming a pattern of an insulating layer on the shielding layer; and forming a pattern of a touch electrode layer on the insulating layer. In the embodiments of the invention, the patterning of the bridging layer and the shielding layer is accomplished simultaneously in one patterning process, thereby the number of patterning times during the manufacture process can be reduced, the manufacture efficiency of the touch screen panel can be improved, and the production cost can be lowered.
