Problems solved by technology

[0003] For a flexible display panel, when it is bent from a flat state to a folded state, the film layer of the foldable flexible display device located on the convex side of the neutral plane is subject to tensile stress. Excessive stress will cause the film layer to separate and produce Problems such as cracks and disconnections affect the normal display of the flexible display panel and reduce the service life of the flexible display panel

Abstract

The invention provides a flexible display panel and a display device. The flexible display panel includes a substrate; an inorganic layer which is located at one side of the substrate and comprises a groove area and a non-groove area, wherein the groove area comprises a groove with an opening facing the side away from the substrate; and an organic layer which is located at the side, away from the substrate, of the inorganic layer and comprises a filling part, wherein the projection, in the direction perpendicular to the substrate, of the filling part is located in the groove of the groove area. In at least one first section perpendicular to the substrate, the non-groove area is located at the two sides of the groove area, the surface at the side, away from the substrate, of the filling part is a concave face, and the concave face is concave towards the side of the substrate. The display device comprises the flexible display panel. According to the present invention, the pre-bent surface is firstly formed on the concave surface of the filling part, and when the flexible display panel is bent, the pre-bent surface can counteract the bent surface generated by bending, so that the bending reliability of the flexible display panel is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to the field of flexible display technology, especially to a flexible display panel and a display device. Background technique [0002] The flexible display panel is a deformable and bendable display device, which has the advantages of being convenient to carry, bendable and curlable, etc., so it is a research and development hotspot in the current display technology. [0003] For a flexible display panel, when it is bent from a flat state to a folded state, the film layer of the foldable flexible display device located on the convex side of the neutral plane is subject to tensile stress. Excessive stress will cause the film layer to separate and produce Problems such as cracks and disconnections affect the normal display of the flexible display panel and reduce the service life of the flexible display panel. Contents of the invention [0004] In view of this, the pres...
