Display panel, manufacturing method thereof, display device

A manufacturing method of a display panel, comprising:

• providing a substrate on a base;
• mixing at least one of an organic fluorescent material or an inorganic fluorescent material in a photoresist to form a fluorescent material, and coating the fluorescent material on the substrate to form a fluorescent layer, the fluorescent layer being configured to prevent light from damaging an active layer in a transistor stack in a laser lift-off process;
• providing the transistor stack on the fluorescent layer, wherein an orthographic projection of the fluorescent layer on the base overlaps an orthographic projection of the active layer on the base;
• and
• lifting off the base from the substrate by the laser lift-off process.
