Embodiment Construction

[0022] As mentioned in the background art, in the prior art, there is a risk of film peeling between the metal wiring layer and the adjacent film layer when the flexible display panel is bent, so that the yield of the display panel is low. question. The inventor found that the reason for this problem is as follows: the film layer adjacent to the metal wiring layer is usually set as an inorganic insulating layer, and the film layer peeling between the inorganic insulating layer and the metal wiring layer is easy to occur. In order to solve the above problems, the inventor found that by replacing the inorganic insulating layer adjacent to the metal wiring layer with an organic layer, on the one hand, the organic layer can meet the insulation requirements due to its low conductivity; The flexibility of the layer is better than that of the inorganic insulating layer, so it can effectively reduce the risk of film layer peeling between the metal wiring layer and the organic layer. ...

Abstract

The invention provides a display panel, a display device and a preparation method of the display panel. The display panel includes a flexible substrate, and the flexible substrate includes a display area and at least one bending area adjacent to the display area; wherein, an electrode layer is arranged on the display area, and at least one bending area includes: a first organic layer disposed on the flexible substrate the metal wiring layer, electrically connected with the electrode layer, and arranged on the first organic layer; the second organic layer, arranged on the metal wiring layer. The embodiment of the present invention can effectively reduce the risk of delamination between film layers when the bending region of the display panel is bent, thereby improving the yield of the display panel.

Description

technical field [0001] The invention relates to the technical field of display panels, in particular to a display panel, a display device and a method for preparing the display panel. Background technique [0002] With the continuous development of display panel technology, flexible display panels have become a research hotspot. However, when the existing flexible display panel is bent, film layer peeling easily occurs between the metal wiring layer and the adjacent film layer, which reduces the yield of the display panel. Contents of the invention [0003] In view of this, embodiments of the present invention provide a display panel, a display device, and a method for manufacturing a display panel, thereby effectively reducing the risk of peeling off between film layers when the bending region of the display panel is bent, thereby improving the yield of the display panel . [0004] One aspect of the present invention provides a display panel, including: a flexible subst...
