Abstract
A display apparatus includes a unit pixel comprising a red sub pixel, a green sub pixel, a first blue sub pixel, and a second blue sub pixel. Each of the sub pixels include a first electrode, an intermediate layer comprising an organic emission layer disposed on the first electrode, and a second electrode disposed on the intermediate layer. The first blue sub pixel includes a first intermediate layer including a first blue organic emission layer, the second blue sub pixel includes a second intermediate layer including a second blue organic emission layer, the green sub pixel includes a third intermediate layer including a green organic emission layer, and the red sub pixel includes a fourth intermediate layer including a red organic emission layer. The first intermediate layer and the second intermediate layer have different thicknesses, and the third intermediate layer and the fourth intermediate layer have different thicknesses.
