Abstract

Provided are a foldable display panel, a manufacturing method thereof and a foldable display device. The foldable display panel is improved by replacing the conventional inorganic insulating layer with a bending resistant organic insulating layer to improve the bendability of the display panel; meanwhile, the cross-interconnected metal foil layer is added between the organic insulating layers to improve the resilience after bending, thereby improving the reliability of the product while improving the bending resistance of the display panel.
