Patent attributes
An Organic Light Emitting Display (OLED) and its method of fabrication, is capable of omitting a process of patterning a second pixel electrode by forming a first pixel electrode, forming a pixel-defining layer including an opening on the first pixel electrode, and forming the second pixel electrode and a third pixel electrode in the opening using a shadow mask as a mask. The OLED includes: a substrate; a first pixel electrode disposed on the substrate; a pixel-defining layer having an opening exposing a portion of the first pixel electrode; a second pixel electrode disposed on the first pixel electrode exposed by the opening of the pixel-defining layer and disposed in the opening of the pixel-defining layer; a third pixel electrode disposed on the second pixel electrode and disposed in the opening of the pixel-defining layer; an organic layer disposed on the third pixel electrode and including an emission layer; and an opposite electrode disposed on the organic layer.
