Abstract
An organic light-emitting display (OLED) apparatus includes: a first electrode; a second electrode disposed separate from the first electrode; a pixel-defining layer covering an edge of the first electrode and an edge of the second electrode; a first organic functional layer disposed on the first electrode and the pixel-defining layer including a first emission layer; a first opposing electrode covering a top surface and enclosing an outer circumference of side surfaces of the first organic functional layer; a second organic functional layer disposed on the second electrode and the pixel-defining layer including a second emission layer; and a second opposing electrode covering a top surface and enclosing an outer circumference of side surfaces of the second organic functional layer. An area of the first opposing electrode in contact with the pixel-defining layer is greater than an area of the second opposing electrode in contact with the pixel-defining layer.
