  • Publication number: 20150076456
    Abstract: An organic light-emitting display device and a method of manufacturing the organic light-emitting display device. The organic light-emitting display device is a dual emission display capable of displaying differing images on either side of the display, and includes a facing electrode that is selectively deposited in the first area but not in the second area, the selectivity being brought about by a varying an underlying material having differing adhesive forces with the material of the facing electrode. In addition, the underlying materials of the facing electrode and other intermediate layers of the organic light emitting diode device provide extra distance between the organic light emitting layer and a reflective electrode, so that exciton quenching is reduced, resulting in improved light emitting efficiency.
