Abstract

The invention discloses a flexible display panel and a display device. The flexible display panel comprises a substrate which is defined as a display area and a non-display area surrounding the display area, an organic electroluminescent structure which is located in the display area, and an encapsulating film layer which is located in the display area and the non-display area to cover the organic electroluminescent structure. The encapsulating film layer comprises at least two inorganic layers and an organic layer arranged between two inorganic layers. In the non-display area, the inorganic layers are directly laminated with each other. Each inorganic layer located in the non-display area is provided with a groove filled with an organic filler, and the orthographic projections of the organic fillers in different inorganic layers do not overlap on the substrate. Cracks of the inorganic layer edge are avoided when the flexible display panel is bent, and the path of the cracks expanding to the display area is blocked. By using non-overlapping organic fillers, the diffusion path of water-oxygen in adjacent inorganic layers is increased.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible display panel and a display device. Background technique [0002] Currently, OLED (Organic Light-Emitting Diode, organic electroluminescence) devices are considered to be the flat panel display devices with the most development potential, and at the same time considered to be the display technology most likely to be made into flexible display devices. [0003] Existing flexible display panels such as figure 1 As shown, it generally includes: a flexible substrate 01, an organic electroluminescent structure 02 and an encapsulation film layer 03 located on the flexible substrate 01 in sequence, wherein the organic electroluminescent structure 02 is located in the display area. The encapsulation film layer 03 is generally formed by stacking organic layers 031 and inorganic layers 032; the inorganic layer 032 covers the organic electroluminescent structure 02 and the non-...
