Abstract: An organic light emitting display apparatus includes a substrate including a plurality of pixels. The organic light emitting display apparatus further includes a plurality of organic light emitting diodes on the substrate so as to correspond to the plurality of pixels. The plurality of pixels includes a first pixel, a second pixel, a third pixel, and a fourth pixel which emit different color light. Each of the plurality of organic light emitting diodes includes a first electrode, a light emitting portion on the first electrode and a second electrode on the light emitting portion. A thickness of the first electrode of the first pixel is different from a thickness of the first electrode of the second pixel, and the thickness of the first electrode of the second pixel is different from a thickness of the first electrode of the third pixel.
