Display panel and display device, and fabrication methods are provided. The method for fabricating the display panel includes forming a protective layer at least on a bending region, the bending region being in a non-display region containing peripheral circuits of the display panel, to cover the peripheral circuits, and folding the display panel at the bending region towards a back surface of the display panel. When the display panel is folded at the bending region towards the back surface of the display panel, the protective layer coated on the bending region provides protection for the peripheral circuits formed on the surface of the bending region.
