An organic light-emitting display apparatus including: a substrate including a light emission area and a non-emission area disposed in an outer portion adjacent the light emission area; a plurality of subpixels disposed in the light emission area of the substrate and including a first electrode, a emission layer, and a second electrode, wherein the plurality of subpixels respectively emit light of different colors; and a plurality of dummy emission layers that are disposed in a non-emission area of the substrate and are of different colors. A first distance between adjacent dummy emission layers of a first color, from among the plurality of dummy emission layers is smaller than a second distance between adjacent subpixels that emit light of the first color, from among the plurality of subpixels.
