Abstract: An organic light-emitting display panel and a display device are provided. The organic light-emitting display panel includes: a driving device film layer, an anode layer, a pixel definition layer, an organic light-emitting layer, a cathode layer, an encapsulation film layer, and a touch film layer that are sequentially stacked. The encapsulation film layer includes an organic encapsulation layer. The organic light-emitting display panel has a specially-shaped border area and a straight-line border area. In the cathode connection area, in a direction perpendicular to the organic light-emitting display panel, a top end of the cathode layer is higher in the specially-shaped border area than in the straight-line border area, and the top end of the cathode layer is an end of the cathode layer furthest away from the driving device film layer.
