Abstract
An organic light emitting display panel and a display device are provided. In the display panel, an organic light emitting layer is at a side of a blocking layer facing away from a substrate layer, the blocking layer includes a first organic insulating layer and a first inorganic insulating layer between the organic light emitting layer and the first organic insulating layer, and the substrate layer is at a side of the blocking layer facing away from organic light emitting layer. The blocking layer has a groove formed by recessing towards a side near substrate layer. The groove penetrates through the first inorganic insulating layer and is in the first organic insulating layer. In a direction from the display area to the opening area, one groove has an opening size smaller than a maximum size of the one groove. The organic light emitting layer is disconnected at the groove.
