Abstract
Disclosed are a reflective color filter substrate and driving method thereof, and a display panel and a display device. The substrate includes color-resist elements in an array, each color-resist element includes a first and second electrode arranged opposite to each other, and a color-resist structure located between the first and second electrodes; and in each color-resist element: the first electrode is a light-transmission electrode; the first and second electrodes are configured to generate a first electric field, and the color-resist elements are configured to be driven by the first electric field to reflect light rays incident on the first electrode as monochromatic light; and the first and second electrodes are configured to generate a second electric field, and the color-resist elements are configured to be driven by the second electric field to reflect the light rays incident on the first electrode as hybrid light of monochromatic light and white light.
