Organic light emitting display apparatus

An organic light emitting display apparatus is provided which include a plurality of subpixels in an emission region; and a planarization layer (170, figure 2) in the plurality of subpixels, the planarization layer including a plurality of light extraction patterns including a convex portion 143 and a plurality of concave portions 141. At least a first light extraction pattern of the plurality of light extraction patterns is rotated with respect to a centre portion of each of the plurality of concave portions such that the direction between adjacent concave portions is angled with respect to the edges of the display substrate. The light emitting devices in the subpixels may be on, and conformed to the shape of, the concave portions.
