Abstract
A method for making a color image and a color filter manufactured with the method. The color of the color image and the color of the color filter are characterized by resonance features of a Fabry-Perot resonant cavity (100). Through a nanoimprint technology, Fabry-Perot resonant cavities with different thicknesses are manufactured, and the Fabry-Perot resonant cavities with different thicknesses correspond to red, green and blue respectively. The red, green and blue Fabry-Perot resonant cavities are distributed according to the color separation principle, and a combination thereof has the effect of representing a whole image macroscopically.
