Abstract
Example embodiments relate to a reflective structure, a display apparatus including the reflective structure, and a method of manufacturing the reflective structure and the display apparatus. A reflective structure according to example embodiments may include a plurality of nanoparticles of non-uniform size, which are arranged on a substrate, or an uneven element having a surface contour that resembles a plurality of nanoparticles; and a reflective layer covering the plurality of nanoparticles or the uneven element. The reflective layer may have a random/variable height.
