The embodiment of the present invention discloses a display panel, a manufacturing method thereof, and a display device. The display panel includes an array substrate and a touch layer located on one side of the array substrate; the touch layer includes a plurality of first touch electrodes, two adjacent The first touch electrode is electrically connected through the first connection part, the first connection part and the first touch electrode are arranged in different layers, and an insulating layer is arranged between the first connection part and the first touch electrode; the insulating layer includes a first An insulating layer and a second insulating layer, the first insulating layer includes a plurality of first through holes, at least part of the second insulating layer covers the side walls of the first through holes, the second insulating layer includes the second through holes, and the first touch electrode and the first connection part are electrically connected through the second through hole; the vertical projection of the first through hole on the array substrate covers the vertical projection of the second through hole on the array substrate; the Young's modulus of the second insulating layer is smaller than that of the first insulating layer Young's modulus of the layer. The touch function of the display panel has high reliability.
Description
technical field [0001] Embodiments of the present invention relate to display technology, and in particular, to a display panel, a method for manufacturing the same, and a display device. Background technique [0002] Organic Light Emitting Diode (OLED) display devices not only have the advantages of high luminous efficiency, low energy consumption, short response time and wide viewing angle, but also can form flexible displays because they can be fabricated on substrates of different materials. Provide users with better visual effects. [0003] Existing display devices usually integrate a touch function. If the touch layer adopts the mutual capacitive touch solution in which the touch driving electrodes and the touch sensing electrodes are arranged on the same layer, then the adjacent two touch driving electrodes (or touch sensing electrodes) need to pass through vias and different layers. The provided connecting line realizes electrical connection. However, for the flex...
