The embodiment of the invention provides a flexible display panel and a display device. In the flexible display panel provided by the embodiment of the invention, a first bonding layer comprises a first part located in a bending area, at least two gaps are formed in the first part, and the gaps divide at least part of the first part into the plurality of sub-parts which are separated from one another, so that when the flexible display panel is in a bent state, part of stress accumulated at the interface of the first part and a first structural layer and / or a second structural layer can be conducted into the gaps, the part of stress is released through deformation at the gaps, the stress at the interface of the first part can be reduced, the problem that the first part of the first bonding layer is stripped from the first structural layer and the second structural layer which are bonded with the first part of the first bonding layer can be solved, and effective bonding between the first bonding layer and the first structural layer and between the first bonding layer and the second structural layer can be guaranteed.
Description
technical field [0001] The present application relates to the field of display technology, and in particular, the present application relates to a flexible display panel and a display device. Background technique [0002] With the development of display technology, especially the development of OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display technology, more and more OLED flexible display products are currently on the market. In the flexible display panel of the existing OLED flexible display product, the structural layer of the flexible display panel is usually bonded by an OCA (Optically Clear Adhesive, optical adhesive) film layer. [0003] However, during the folding process of the flexible display panel, when the stress on the OCA film layer (belonging to the adhesive layer) in the bending area is relatively large, the deformation of the OCA film layer exceeds the design threshold, resulting in the OCA film layer being different from the flexib...
