Abstract

The embodiment of the invention discloses a display panel. In the display panel, a first backplane is arranged in a terminal area; a flexible substrate comprises a first part arranged in the terminal area, and the first part is arranged on the first backplane; a part of a reinforcing layer is arranged on the flexible substrate and is located in the terminal area; a first protection layer is arranged on the first part and spaced away from the reinforcing layer; and a second protection layer is arranged on the first protection layer and connected with the reinforcing layer. In the terminal area, the first protection layer and the second protection layer are arranged on the flexible substrate, and the second protection layer is connected with the reinforcing layer, so that the risks of warping of the terminal area and breakage of metal wires on the flexible substrate are reduced.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel. Background technique [0002] During the research and practice of the prior art, the inventors of the present application found that with the development of the flexible display technology, the size of the product is getting bigger and bigger, and the size of the terminal area of ​​the display module is gradually getting bigger along with it. The larger the size of the terminal area, the easier it is for the edge of the terminal area to warp during the bending process, and even cause the metal wiring to break. Contents of the invention [0003] The embodiment of the present application provides a display panel, which can reduce the risk of warpage in the terminal area and the breakage of metal wires in the area. [0004] An embodiment of the present application provides a display panel, which includes a display area, a bending area, and a terminal a...
