<p>Provided is an organic light-emitting display apparatus that can display a color image without a color filter and prevent a reduction in contrast due to the reflection of external light. The organic light-emitting display apparatus includes: a substrate (1); an organic light-emitting device (3) disposed on the substrate and emitting white light; a sealing member (5) disposed on the organic light-emitting device; a dichroic layer (22) comprising ellipsoidal shaped metal particles which are imprinted on one surface of the substrate and allowing light of a predetermined wavelength band to be transmitted therethrough according to an aspect ratio of the metal particles; and a 1/4 wavelength layer (21) deposited on one of surfaces formed by the substrate and the dichroic layer, and disposed farther away from a direction in which an external light is incident than the dichroic layer, wherein an image is displayed towards the substrate.
