Abstract: Discussed in an organic light emitting display apparatus, which can include a plurality of pixels on a substrate, each pixel including a plurality of subpixels, and each of the plurality of subpixels having an emission region, a planarization layer including a light extraction pattern, the light extraction pattern disposed at the emission region of each of the plurality of subpixels and including a plurality of concave portions; and a light emitting device layer on the light extraction pattern of each of the plurality of subpixels. The emission region of each of the plurality of subpixels includes a reference point disposed at a concave portion of the plurality of concave portions. The light extraction pattern of each of the plurality of subpixels has a rotation angle with respect to the reference point.
