Abstract
Provided is a refractive-index-matching thin film, which is an inorganic crystal thin film, wherein a matching layer including inorganic films having different refractive indices is formed on the surface of a substrate and, more particularly, to a refractive-index-matching thin film, which is configured such that a matching layer including one or more inorganic films having different refractive indices is formed on the surface of a substrate made of a polymer, ceramic, metal or combinations thereof, thus protecting the surface of flexible displays such as curved and bendable displays.
