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 apparatus. The flexible display panel comprises a substrate; an inorganic layer located at one side of the substrate; and an organic layerlocated at one side, far from the substrate, of the inorganic layer. The inorganic layer comprises a groove area and non-groove areas, the groove area comprises a groove whose opening is arranged towards one side far from the substrate, the organic layer comprises a filling portion, the projection of the filling portion in a direction vertical to the substrate is located in the groove of the groove area, and in at least one first cross section vertical to the substrate, the non-groove areas are located at two sides of the groove area. The surface, far from the side of the substrate, of the filling portion is a recessed surface; and the recessed surface is recessed towards the side of the substrate. The display apparatus comprises the above flexible display panel. According to the flexibledisplay panel and the display apparatus, a pre-bent surface is firstly formed on the recessed surface of the filling portion so that when the flexible display panel is bent, the pre-bent surface anda bending surface generated by bending can be offset, and 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...
