A flexible display screen and a method for manufacturing a flexible display screen are provided. The flexible display screen includes a flexible substrate, a thin-film transistor layer, an organic electroluminescent layer, and a flexible cover plate. The thin-film transistor layer is stacked on the flexible substrate and includes a driving section and a packaging section arranged around the driving section, where the packaging section is provided with at least one elongated groove, and at least two long protrusions corresponding to the groove. Two adjacent protrusions are located on both sides of the length direction of the groove. The organic electroluminescent layer is accordingly disposed on the driving section, and the flexible cover plate is stacked on a side of the organic electroluminescent layer that departs from the driving section and covers the organic electroluminescent layer and the packaging section.
