Abstract: The present invention provides a display panel, a manufacturing method thereof, and a display device. The display panel comprises a base substrate, an opposite substrate, a first electrode, a second electrode, and a plurality of original sub-pixels on at least part of which conversion sub-pixels are provided, and an upper water layer is provided on each of the conversion sub-pixels. The conversion sub-pixel is configured to, when an electric field is generated between the first and second electrodes, shrink to one side of the original sub-pixel so that the upper water layer covers the original sub-pixel from above, and, when no electric field is generated between the first and second electrodes, cover the original sub-pixel located under the conversion sub-pixel from above.
