Abstract

The invention describes a display panel and a display device. A plurality of alternately arranged recessed structures and raised structures are disposed in mutually perpendicular first and second directions on an organic insulating layer of the bending region, which, on one hand, can disperse the bending external force during the bending of the bending region, enhance the flexibility of the display panel, and overcome the problem of poor flexibility of the bending region caused by the thick organic insulating layer in the prior design; and, on the other hand, can also reduce the stress on thesignal lines on the organic insulating layer, prevent the signal line from being damaged by the bending external force, increase the distance between adjacent signal lines, avoid signal crosstalk, andimprove the reliability of the display panel.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] With the development of panel displays, the demand for products with high screen-to-body ratio is increasing. [0003] Full-screen borderless display products can enable users to get a better viewing experience. Pad bending (PadBending) is the core technology of full-screen borderless display products. But like figure 1 As shown, figure 1 It is a schematic structural diagram of a flexible display panel in the prior art. The flexible display panel includes a display area 100' and a bending area. Generally, the inorganic insulating layer 101' is brittle. Pad Bending will cause cracks in the inorganic insulating layer 101' in the bending area of ​​the display product, and the cracks will easily extend to the signal line layer 102 ', causing the display to fail. In order to avoid cracks in the inorganic insulat...
