An organic light emitting display apparatus can include a substrate including a plurality of pixels, a transistor on the substrate, an over coating layer on the transistor, a plurality of organic light emitting diodes on the over coating layer corresponding to the plurality of pixels, an encapsulation layer on the plurality of organic light emitting diodes, an adhesive member on the encapsulation layer, and an encapsulation substrate on the adhesive layer. Also, the plurality of pixels include at least first, second and third pixels that emit different color lights, and each of the plurality of organic light emitting diodes includes a first electrode on the over coating layer, a light emitting portion on the first electrode, and a second electrode on the light emitting portion. Also, the light emitting portion includes a first light emitting portion and a second light emitting portion, and elements have certain thicknesses and spatial arrangements.
