Abstract: A reflective display panel is provided, wherein a color-generating layer of the reflective display panel includes optical grating patterns on reflective electrodes, and the optical grating patterns are configured to control a passage of light of different wavelengths. A nano-imprint technology is utilized to form the optical grating patterns with different shapes, heights, widths, period lengths, and space ratios to achieve control a passage of light of different wavelengths, so that the color-generating layer generates different monochromatic light, and light emitted by each sub-color-generating layer is brighter and has purer color.

Abstract: A display panel includes a substrate. A color film layer is formed on the substrate. The color film layer includes first color resistances and second color resistances, first color quantum dots are disposed in the first color resistances, and second color quantum dots are disposed in the second color resistances. The color film layer further includes reflecting color resistances, the reflecting color resistances are formed between the first color resistances and the second color resistances. Reflectivities of contact surfaces between the reflecting color resistances and the first color resistances and between the reflecting color resistances and the second color resistances are greater than 70%, to make first color incident light emitted by the quantum dots of the first color resistances and second color incident light emitted by the quantum dots of the second color resistances to be reflected back to color resistances to excite the quantum dots to illuminate.

Abstract: The present disclosure provides a display panel and display device. The display panel includes a substrate and a color film layer formed on the substrate. A plurality of first color resistances are formed in the color film layer, a plurality of green or red quantum dots are formed in the first color resistances. A first shielding layer is formed on the first color resistances, and the first shielding layer is made of yellow photoresistance material or red photoresistance material. The present disclosure provides a display panel and display device to improve color purity of green light or red light emitted by the quantum dots excited in the color resistance.
