摘要： A flexible display panel and a flexible array substrate are provided, which include a flexible substrate, a thin film transistor layer, and an organic planarization layer. The thin film transistor layer is disposed on the flexible substrate and in a display area and includes a plurality of insulating layers disposed in a stack, wherein, a surface of the thin film transistor layer away from the flexible substrate is provided with first through-holes penetrating at least one of the insulating layers. The organic planarization layer covers one side of the thin film transistor layer away from the flexible substrate and is filled in the first through-holes.
