Abstract
The present invention discloses an organic light-emitting display panel, a manufacturing method thereof, and an encapsulation film thereof. In this invention, an auxiliary encapsulation layer is disposed on an outer side of an inorganic layer, and the auxiliary encapsulation layer at least covers a bending region of the inorganic layer and a boundary region of the inorganic layer. Even if the inorganic layer cracks or peels in the bending region and the boundary region, a channel of water and oxygen generated at a cracked place or a peeling place is blocked by the auxiliary encapsulation layer, thereby ensuring an ability of the encapsulation film to block water and oxygen into an organic light-emitting device.
