Abstract

The invention provides a display panel. The display panel comprises a substrate, an inorganic layer arranged on the substrate and a metal layer arranged on the inorganic layer, wherein the inorganic layer comprises a barrier layer arranged on the substrate and an insulating layer arranged on the barrier layer; the metal layer comprises a plurality of metal wires; an opening penetrating through the insulating layer is formed in the inorganic layer in a bending region; and an organic layer fills the opening. According to the invention, the barrier layer is arranged in the opening to prevent water and oxygen from corroding the metal wires, the organic layer is arranged in the opening to release stress, cracks are prevented from diffusing to the metal wires, and the bending resistance of the display panel is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel. Background technique [0002] With the continuous development of display technology, in order to realize the design of a flexible display panel or a full screen, it is usually necessary to set a bending area. [0003] figure 1 It is a structural schematic diagram of a display panel in the prior art, such as figure 1 As shown, the display panel includes from bottom to top: a base substrate 20, an inorganic layer 30 and a metal layer 36, wherein the inorganic layer 30 is a stacked structure, including a barrier layer 31, a buffer layer 33, a gate insulating layer 34 and Interlayer insulation layer 35; the display panel also includes a bending area 10, when the display panel is bent in the bending area 10, the bending area 10 will bear too concentrated stress, due to the hardness of the inorganic layer 30 in the bending area 10 Large, so that the stres...
