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.
