  • Organic light-emitting display device and method of manufacturing the same
    Patent number: 9293515
    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.
