Abstract: A display device that includes a substrate, a display element disposed on the substrate and having a pixel electrode, an emission layer, and an opposite electrode, an inorganic functional layer disposed on the opposite electrode and including a first element, and a thin-film encapsulation layer disposed on the inorganic functional layer, wherein the inorganic functional layer includes a first film and a second film disposed on the first film. In each of the first film and the second film, a stoichiometric ratio of the first element decreases as distance from the substrate increases. The first element may be one of silicon (Si), titanium (Ti), aluminum (Al), hafnium (Hf), indium (In), tin (Sn), chromium (Cr), manganese (Mn), iron (Fe), tantalum (Ta), zinc (Zn), and a combination thereof.
