The present invention provides a flexible touch display panel and a manufacturing method therefor, and a display device, relating to the field of display technologies, and enabling a touch display panel to be foldable. The flexible touch display panel comprises: a flexible display substrate; a color film layer provided above the flexible display substrate, the color film layer comprising a plurality of color filter blocks arranged in a spaced manner; and light blocking layers provided between the color filter blocks, metal grid electrode patterns and strip bridging electrode patterns located at both sides of the light blocking layers. The orthographic projection of the light blocking layers on the flexible display substrate covers the orthographic projection of the metal grid electrode patterns and the strip bridging electrode patterns on the flexible display substrate. The metal grid electrode patterns comprise a plurality of first electrodes and a plurality of second electrodes which are insulated from each other and intersect. The strip bridging electrode patterns comprise a plurality of strip bridging electrodes arranged in parallel. One of the first electrode and the second electrode is electrically connected to the strip bridging electrodes by means of vias provided on the light blocking layer.
