Flexible display panel, manufacturing method thereof and display device

A manufacturing method of a flexible display panel, comprising:

• providing a first flexible substrate;
• forming a plurality of polymer walls on a surface of the first flexible substrate;
• forming a liquid crystal display layer in gaps of the plurality of polymer walls on the surface of the first flexible substrate;
• forming a black matrix grid on the liquid crystal display layer;
• and
• providing a second flexible substrate on the black matrix grid, and cell-assembling the second flexible substrate with the first flexible substrate.

A manufacturing method of a flexible display panel, comprising:

• providing a base panel, the base panel comprising:
• a first flexible substrate and a second flexible substrate cell-assembled with the first flexible substrate, and a liquid crystal display layer located between the first flexible substrate and the second flexible substrate;
• performing an irradiating and etching process to the base panel by using a mask provided with a grid pattern, to form a plurality of polymer walls on the first flexible substrate;
• and
• forming a touch layer at a side of the second flexible substrate away from the first flexible substrate by using the mask provided with the grid pattern.
