Abstract: According to example embodiments, a reflective film includes a plurality of first concave-convex elements having a curved surface and a plurality of second concave-convex elements on the curved surface. The second concave-convex elements may be a smaller scale than a scale of the plurality of first concave-convex elements. The reflective structure may further include a color purity control element configured to reduce degradation of a color purity expressed by the reflective film. The color purity control element may be configured such that at least a complementary light with respect to a color light reflected by the reflective film travels in the same direction as the reflected color light.

Abstract: Provided are a reflective structure, a display apparatus including the reflective structure, and methods of manufacturing the reflective structure and the display apparatus. The reflective structure may include a reflective layer having a multiple uneven structure. The reflective layer may have a curved surface as a result of a plurality of first uneven portions, and wherein the curved surface may has a plurality of second uneven portions having a scale less than that of the first uneven portions. The plurality of first uneven portions may have a micro-scale size, and the plurality of second uneven portions may have a nano-scale size. The reflective layer may be arranged on a lower structure including a plurality of nanoparticles. A flexible material layer may be formed on the reflective layer.

Abstract: A surgical implement is disclosed for performing in combination a retracting and illuminating function within body cavities formed during surgery. The retraction function is performed by a blade, which can be segmented for flexible bending, mounted generally at right angles to a support shaft manipulatable by a handle. Miniature lamps present in the blade and powered by small batteries located in the handle perform the illumination function within the body cavity around which the retraction function is simultaneously performed.
