Reflective three-dimensional display device and method for production thereof

A reflective three-dimensional display device and method for production thereof are disclosed. This method includes following steps: providing a substrate with at least a groove and at least a metal particle, and then tilting the substrate such that the groove has a first and second angles along the first and second directions with respect to the horizontal plane. When the metal particle is located in the groove, the metal particle would be self-assembled to the lowest potential energy state, and then an adhesive layer and glue are provided for transferring the metal particle and fixed the relative position of the metal particle and fixed the relative position of the metal particle. Among which, a surface of the metal particle is exposed, wherein the surface is used for reflecting at least a light to a three-dimensional space, in order to achieve uncorrected visual three-dimensional images and reduce the effect of the perspective phenomenon of the volumetric three-dimensional images.
