Claim 8:
9. A flexible display panel, comprising a display region and a non-display region arranged around the display region,
wherein the flexible display panel comprises a base substrate, a thin film transistor (TFT) array layer disposed on the base substrate, and an encapsulation layer disposed on the TFT array layer; and
wherein the TFT array layer comprises an inorganic layer, an organic layer disposed on the TFT array layer and positioned in the non-display region, the organic layer is provided with a hollow structure at least penetrating the organic layer, and the encapsulation layer covers the hollow structure;
wherein the organic layer comprises one or more of a planarization layer, a pixel definition layer, and a support layer sequentially disposed on the TFT array layer, the planarization layer and the pixel definition layer extend from the display region to the non-display region, and the hollow structure further penetrates the support layer; and
wherein a length of an orthographic projection of the planarization layer on the base substrate is less than a length of an orthographic projection of the pixel definition layer on the base substrate.
