Abstract:
An organic light-emitting display apparatus including; a first pixel electrode, a second pixel electrode, a third pixel electrode; a first lower functional layer, a second lower functional layer, and a third lower functional layer; a first organic emission layer for emitting a first color, a second organic emission layer for emitting a second color, and a third organic emission layer for emitting a third color; an opposite electrode; and a first upper functional layer, a second upper functional layer, and a third upper functional layer respectively disposed between the opposite electrode and the first organic emission layer, the second organic emission layer, and the third organic emission layer and each having a thickness that is equal to or greater than about 1300 Å and less than or equal to about 1800 Å.
