Abstract
The present invention provides a flexible display panel and a manufacturing method thereof. The flexible display panel includes a flexible substrate, a thin film transistor, a planarization layer having a non-through groove, an anode layer, a pixel defining layer having a through groove, and a photoresist supporting element. The present invention utilizes a patterning structure of the pixel defining layer and the planarization layer to reduce internal stress of the flexible substrate, so as to improve dynamic bending performance of the flexible substrate.
