Reflective Three-Dimensional Display Device and Method for Manufacturing the Same

A reflective 3D display device and manufacturing method thereof This method includes following steps: providing a template with at least one concave parts-trap and at least one metallic microsphere, and tilting the template to form a first included angle, between the concave parts-trap and a horizontal plane, in a first direction, and a second included angle, between the concave parts-trap and the horizontal, in a second direction. When the metallic microspheres are disposed in the concave parts-trap, the metallic microspheres would self-organize to intrinsic potential minima, and then an adhesive layer and a gel are provided for removing which and fixing the relative positions between which respectively. A portion of each metallic microsphere is exposed form the gel, which is used to reflect light to 3D space, such that 3D images viewable with naked eye are achieved and the perspective phenomenon occurring in 3D images is reduced.
