Manufacture method of flexible display panel

A manufacture method of a flexible display panel, comprising steps of:

• step 1, providing a rigid substrate, and forming a plurality of grooves which are separately located on the rigid substrate;
• step 2, respectively forming a plurality of flexible supporting bases in the plurality of grooves;
• step 3, manufacturing a display element layer on the rigid substrate and the flexible supporting bases to obtain a flexible display mother board;
• step 4, cutting the flexible display mother board along edges of the plurality of grooves to obtain a plurality of flexible substrate units, and the flexible substrate unit comprising the rigid substrate, the flexible supporting base and the display element layer from bottom to top in order;
• step 5, stripping the flexible supporting bases in the flexible substrate units from the rigid substrate to obtain a plurality of flexible display panels, and the flexible display panel comprising the flexible supporting base and the display element layer located on the flexible supporting base;
• wherein the rigid substrate is a glass substrate;
• in step 1, a physical method or a chemical method is used to form the plurality of grooves which are separately located on the rigid substrate.
