Abstract: A driving base plate includes a functional region (A) and a peripheral region (B) surrounding the functional region (A). Both the functional region (A) and the peripheral region (B) include a supporting substrate, and the functional region (A) further includes a flexible substrate and at least one protecting layer that are sequentially arranged on the supporting substrate. The region of the orthographic projection of the flexible substrate on the supporting substrate is located within the region where the supporting substrate within the functional region (A) is located, and the protecting layer covers the surface of the flexible substrate further from the supporting substrate and the side of the flexible substrate close to the peripheral region (B). The adhesive force between the flexible substrate and the supporting substrate of the driving base plate is increased, and the reliability of the products manufactured by using the driving base plate is improved.

Abstract: A touch panel, a manufacturing method thereof and a display device are provided. The touch panel includes a first touch electrode, a second touch electrode and a one-piece insulating element. The second touch electrode includes an electrode section disposed in a same layer as the first touch electrode and a connecting section under the electrode section. The electrode section includes a first electrode section and a second electrode section, which are electrically connected by the connecting section, and the connecting section is spaced apart from the first touch electrode. The insulating element includes a first insulating section between the connecting section and the first touch electrode and a second insulating section between the first electrode section and the first touch electrode and also between the second electrode section and the first touch electrode. The insulating sections can be obtained by performing a patterning process, so that the manufacturing method of the touch panel is simplified.
