There are provided an optically-functional film allowed to prevent peeling due to adhesion failure or deterioration due to moisture diffusion and a method of manufacturing the same, and a display allowed to prevent a decline in luminance and a color change depending on a viewing angle and a method of manufacturing the same. The optically-functional film includes: an intermediate layer, made of an insulating material including silicon, and having silicon-containing particles therein or on a top surface thereof; and an outermost layer made of the same material as that of the intermediate layer, whereas having a density higher than that of the intermediate layer, and having a bottom surface in contact with a top surface of the intermediate layer and a top surface with asperities.
