Abstract
A display panel is provided, including a substrate on a base, a transistor stack on the substrate, and a fluorescent layer between the base and the transistor stack. The fluorescent layer is configured to prevent light from damaging an active layer in the transistor stack in a laser lift-off process, and an orthographic projection of the fluorescent layer on the base overlaps an orthographic projection of the active layer on the base. A display device comprising the display panel, and a manufacturing method of the display panel are further provided.
