Abstract
An optical film capable of preventing reflection of external light, and an organic light emitting display (OLED) apparatus including the same, are disclosed. The optical film is disposed on a substrate of an organic light emitting display, and comprises a first substrate, a first electrode, a light emitting unit comprising a plurality of organic light emitting elements, and a second electrode sequentially formed on the first substrate. The second substrate concentrates light emitted from the light emitting unit so as to emit outward, and absorbs external light so as to prevent the external light from being reflected.
