Abstract: An OLED display panel and a method for manufacturing the same are provided. By successively forming a first organic film layer, a metal film layer, and a second organic film layer on a substrate layer, a width of the metal film layer is greater than a width of the first organic film layer in a peripheral region of the OLED display panel, to form an inverted trapezoid-shaped bottom-cut structure. An included angle between an edge of the first organic film layer and the metal film layer is relatively large, and if an inorganic film layer is further formed subsequently, the inorganic film layer may have a relatively small thickness at this position, which makes it easier for a crack to occur and a fracture to appear, as such, when cutting is performed using a laser, splitting of the inorganic film layer will be terminated at this position.
