Abstract
An organic light-emitting display (OLED) apparatus includes: a first electrode; a first organic functional layer disposed on the first electrode, the first organic functional layer including a first emission layer; a first opposing electrode covering a top surface and side surfaces of the first organic functional layer; a second electrode disposed separate from the first electrode; a second organic functional layer disposed on the second electrode, the second organic functional layer including a second emission layer; and a second opposing electrode covering a top surface and side surfaces of the second organic functional layer, wherein a lateral thickness of the first opposing electrode covering the side surfaces of the first organic functional layer is greater than a lateral thickness of the second opposing electrode covering the side surfaces of the second organic functional layer.
