Abstract
Discussed is a manufacturing method of a micro mirror array including forming a mirror surface on a polymer film, bonding a plurality of polymer films, each having the mirror surface formed thereon, cutting the bonded polymer films to manufacture a primary micro mirror array, forming an additional mirror surface on the manufactured primary micro mirror array, bonding a plurality of primary micro mirror arrays, each having the additional mirror surface formed thereon, and cutting the bonded primary micro mirror arrays. The micro mirror array is used to form a high-quality floating image.
