Patent ID: 8581270

Claim:
An organic light-emitting display apparatus comprising: a first sub-pixel, a second sub-pixel, and a third sub-pixel, wherein each of said first, second and third sub-pixels displays a different color; a substrate; a first electrode disposed on the substrate; a second electrode disposed on the first electrode, facing the first electrode; an organic emission layer disposed between the first electrode and the second electrode, comprising a first organic emission layer, a second organic emission layer, and a third organic emission layer; and an electron acceptor layer disposed between the first electrode and the second electrode configured to contact the organic emission layer, wherein the first organic emission layer is disposed in the first sub-pixel, the second organic emission layer is disposed in the second sub-pixel, and the third organic emission layer is commonly disposed over the first sub-pixel, the second sub-pixel, and the third sub-pixel; and wherein the electron acceptor layer is disposed only between the first organic emission layer and the third organic emission layer in the first sub-pixel and between the second organic emission layer and the third organic emission layer in the second sub-pixel.
