Abstract
A flexible display panel is provided, which includes a base substrate, a thin film transistor (TFT) array layer, and an encapsulation layer. The TFT array layer includes an inorganic layer. An organic layer is disposed on the TFT array layer in a non-display region. The organic layer is defined with a hollow structure at least penetrating the organic layer and the encapsulation layer covers the hollow structure. The organic layer includes a planarization layer, a pixel definition layer, and a support layer. The hollow structure includes grooves with different groove levels, which improves a bending resistance of the flexible display panel and prevents cracks from extending to a display region.
