Abstract

An organic light-emitting display panel, a method for manufacturing the same and an organic light-emitting display device are provided. The organic light-emitting display panel includes a flexible substrate comprising a display region, an aperture region surrounded by the display region, and a first non-display region located between the display region and the aperture region, a thin film transistor layer arranged on the flexible substrate, a light-emitting device layer arranged on the thin film transistor layer and including a first electrode, a light-emitting layer, and a second electrode, an encapsulation layer arranged on the light-emitting device layer and sequentially including a first inorganic encapsulation layer and a first organic encapsulation layer, and borders of the second electrode and the first inorganic encapsulation layer in the first non-display region are aligned, and an inorganic layer covering the borders of the second electrode and the first inorganic encapsulation layer.
