ABSTRACT:
An organic light-emitting device and methods of forming the same are provided. The organic light-emitting device includes: a substrate having a pixel area and a peripheral circuit area; a reflective layer on the substrate, the reflective layer having a first reflective part in the pixel area and a second reflective part in the peripheral circuit area; a first electrode layer having a first part on the first reflective part; a pixel definition layer on the substrate, the pixel definition layer forming a plurality of pixel openings to expose a portion of the first part of the first electrode layer and at least one electrode contact hole to expose the second reflective part; an organic light-emitting layer on the first electrode layer; and a second electrode layer on the organic light-emitting layer, the second electrode layer extending to the peripheral circuit area to electrically couple with the exposed area of the second reflective part.
