Abstract

The present disclosure relates to a display device, a display panel and a manufacturing method thereof, and relates to the field of display technology. The manufacturing method includes: providing a substrate, the substrate includes a display area and a peripheral area, and the peripheral area includes a binding area; forming a driving layer located in the display area and a binding layer located in the binding area on the substrate; the driving layer includes a gate layer and a first source and drain layer; the binding layer includes a conductive layer and a transfer layer, and the transfer layer and the first source and drain layer are arranged in the same layer; a passivation layer covering the transfer layer and the first source and drain layer is formed; A light-emitting functional layer is formed on the side of the passivation layer facing away from the substrate corresponding to the display area; a first touch electrode layer is formed on the side of the light-emitting functional layer facing away from the substrate; and a first touch electrode layer is formed on the side of the passivation layer facing away from the substrate A touch dielectric layer; a through hole at least partially exposing the transfer layer is formed in the area of ​​the touch dielectric layer corresponding to the binding area; and a second touch electrode layer covering the transfer layer and the touch dielectric layer is formed.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular, to a display device, a display panel, and a manufacturing method of the display panel. Background technique [0002] At present, OLED (Organic Light-Emitting Diode, organic light-emitting diode) display panels are more and more widely used. The OLED display panel usually needs to be bound to the driving circuit board through the bonding pads on its own edge, so as to receive the driving signal and realize the functions such as display and touch. However, the bonding pad is prone to poor bonding, which affects the normal transmission of the driving signal and is not conducive to ensuring the display effect. [0003] It should be noted that the information disclosed in the above Background section is only for enhancement of understanding of the background of the present disclosure, and therefore may contain information that does not form the prior art that is already k...
