Abstract
A display device and a manufacturing method thereof are disclosed. The display device comprises an upper substrate (103), a lower substrate (104), a solvent (102), and ellipsoids (101), and the solvent (102) and the ellipsoids (101) are provided between the upper substrate (103) and the lower substrate (104). The ellipsoids are configured for forming photonic crystals and have electromagnetic characteristics. By means of photonic crystals formed by the ellipsoids having a shape of oval spheres with a size in order of nanometer or sub-micrometer, the display device can change wavelength of reflected light and present different colors, thus color images can be displayed.
