Abstract: A display panel and a manufacturing method thereof, and a display device are provided. The display panel includes a display area and a non-display area disposed adjacent to the display area, and includes a substrate, and a thin-film transistor layer, a passivation layer, a planarization layer, a protective layer, and an anode that are disposed and stacked on the substrate; the thin-film transistor layer includes a wiring portion disposed in the non-display area, and an orthographic projection of the protective layer on the thin-film transistor layer at least covers the wiring portion. By providing the protective layer between the planarization layer and the anode, the anode is thereby prevented from contacting with foreign matters on the planarization layer, alleviating a risk of dark spots appearing on the display panel.
