Abstract
The present disclosure provides an organic light-emitting display panel, a method for preparing the same and a display device. The method includes: providing a substrate, where the substrate includes a non-display area and a display area surrounding the non-display area; forming a barrier layer and a pixel circuit on the substrate, where an orthographic projection of the pixel circuit on the substrate and an orthographic projection of the non-display area on the substrate do not overlap; patterning the barrier layer in the non-display area to form at least one via hole penetrating the barrier layer; patterning the substrate by using the barrier layer as a mask in the non-display area to form a groove; forming a light emitting layer on the pixel circuit; and forming a thin film encapsulation layer covering the light emitting layer and the side wall of the draw-in structure on the light emitting layer.
