Abstract

The invention relates to a flexible display panel and a flexible display device. The flexible display panel comprises a flexible substrate, a first inorganic layer, a stress relief layer, multiple wires, an insulation layer and a second inorganic layer, wherein the flexible substrate comprises a bent area; the first inorganic layer is arranged on the flexible substrate, and the first inorganic layer in the bent area comprises a groove; the stress relief layer fills the groove; the multiple wires are arranged on the first inorganic layer and the stress relief layer; the insulation layer coversthe multiple wires; the second inorganic layer is arranged at least one end of the bent area and comprises a first part and a second part, the first part is contacted with the insulation layer and thesecond part is contacted with the first inorganic layer. the contact performance between the wire and the first inorganic layer can be effectively improved, the wire is thus pinned by the second inorganic layer, and the phenomenon that film peeling or warping happens to two ends of the bent area in the case of bending and signal transmission is influenced can be prevented.

Description

technical field [0001] The invention relates to the technical field of flexible display, in particular to a flexible display panel and a flexible display device. Background technique [0002] With the development of science and technology, portable devices have become a new development trend in modern society, and are gradually changing human life and bringing major changes to science and technology. In particular, the flexible display panel is more and more favored by users due to its advantages of being foldable, easy to carry, and wide application range, and provides users with a brand-new viewing experience. [0003] In the related art, the flexible display panel often has the phenomenon that metal wires are broken in the bending area or the film layer of the metal wires is peeled off in the bending area, resulting in display defects. Contents of the invention [0004] In view of this, the present invention provides a flexible display panel and a flexible display devi...
