| Zusammenfassung: | A retroreflective structure is disclosed in the present invention and includes a substrate, a plurality of microspheres and at least one photonic crystal layer. The microspheres are disposed on the substrate, and the photonic crystal layer covers the microspheres and the substrate. Accordingly, the retroreflective structure of the present invention has advantages such as wide observation angle and controllable reflecting color for improving the efficiency and the additional value of the retroreflective structure. |
