Organic light emitting display apparatus

An organic light emitting display apparatus, comprising:

• a first subpixel, a second subpixel, and a third subpixel on a substrate, wherein:
• each of the first, second, and third subpixels includes a passivation layer on the substrate, a first electrode on the passivation layer, an intermediate layer on the first electrode and including an organic emission layer, and a second electrode on the intermediate layer,
• the second subpixel further includes a second subpixel light conversion layer that includes an oxide semiconductor, the second subpixel light conversion layer being on the substrate, and the second subpixel passivation layer being on the light conversion layer, and
• the third subpixel further includes a third subpixel light conversion layer on the substrate, and further includes an insulation layer on the third subpixel light conversion layer, the third subpixel light conversion layer including an oxide semiconductor, the third subpixel passivation layer being on the insulation layer.
