Abstract
An anti-reflection structure, a display device and a fabrication method for the anti-reflection structure are provided. The anti-reflection structure comprises a substrate, a first microstructure and a second microstructure. The first microstructure comprises a plurality of first microstructure units periodically arranged on the substrate, a second microstructure is filled between the first microstructures so as to cover the substrate, and the anti-reflection structure has a flat surface. The refractive indices of the first microstructure and the second microstructure are different and are configured such that overall, the reflectivity of the anti-reflection structure to light of a predetermined wavelength is lower than the reflectivity of the substrate to light of the predetermined wavelength.
