Abstract

The embodiment of the invention provides a flexible display panel and a display device, and relates to the technical field of flexible display. The flexible display panel comprises a flexible substrate, an inorganic layer and a plurality of signal lines, wherein the inorganic layer is arranged on the flexible substrate, the plurality of signal lines are arranged in the inorganic layer in parallel along a first direction, are electrically connected with a display unit and extend to a wiring region along a second direction, and the inorganic layer comprises a signal isolation region and a plurality of signal line coverage regions; on a plane where the flexible substrate is located, the orthographic projection of the signal line isolation region and the projections of the plurality of signal lines are not overlapped, and the orthographic projections of the plurality of signal line coverage regions cover the signal lines; and in a direction perpendicular to the flexible substrate, a top end of the inorganic layer on the signal line isolation region is higher than a top end of the inorganic layer on the signal line coverage regions. With the flexible display panel provided by the embodiment of the invention, the top end of the inorganic layer on the signal line coverage regions can be enabled to firstly bear stress during the bending process, so that the stress of the signal lines is reduced, and the probability of signal line breakage is reduced.

Description

[0001] 【Technical field】 [0002] The present invention relates to the technical field of flexible display, in particular to a flexible display panel and a display device. [0003] 【Background technique】 [0004] At present, flexible display screens are not installed on glass but on flexible substrates, which include display areas and surrounding areas, such as figure 1 as shown, figure 1 It is a schematic cross-sectional structure diagram of a flexible display panel in the prior art. The flexible substrate 1 is provided with an inorganic layer 2 and a signal line 3 inside the inorganic layer 2. The inorganic layer 2 mainly plays an insulating role. In order to prevent the inorganic layer 2 from cracking After the crack expands, the inorganic layers 2 at different signal lines 3 are separated from each other, the signal line 3 extends from the display area to the peripheral area, and the flexible substrate 1 in the peripheral area is bent to the side away from the signal line ...
