Organic light emitting display apparatus

An organic light emitting display apparatus, comprising:

• a substrate including a plurality of pixels;
• and
• a plurality of organic light emitting diodes on the substrate so as to correspond to the plurality of pixels,
• wherein the plurality of pixels includes a white pixel, a red pixel, a green pixel, and a blue pixel,
• each of the plurality of organic light emitting diodes includes:
• a first electrode;
• a first light emitting portion on the first electrode and including a blue light emitting layer;
• a second light emitting portion on the first light emitting portion and including a red light emitting layer and two yellow-green light emitting layers;
• a third light emitting portion on the second light emitting portion and including a blue light emitting layer;
• and
• a second electrode on the third light emitting portion,
• wherein a thickness of the first electrode of the white pixel is different from a thickness of the first electrode of the red pixel, and the thickness of the first electrode of the red pixel is different from a thickness of the first electrode of the green pixel.
