Organic light-emitting display device and method of manufacturing the same

摘要

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.

主权项

1. An organic light-emitting display (OLED) device, comprising:
a plurality of pixels, each of the pixels including a first area in which light is emitted from the display device in a first direction and not in a second direction opposite to the first direction, a second area in which light is emitted from the display device in the second direction and not in the first direction and a third area that is transparent to external light; a plurality of first electrodes arranged within the first area of each of the plurality of pixels; a plurality of second electrodes arranged within the second area of each of the plurality of pixels; an intermediate layer arranged on the plurality of first electrodes and the plurality of second electrodes, the intermediate layer including an organic emitting layer; a third electrode arranged on the intermediate layer and within both the first area and the second area; a first auxiliary layer arranged on the third electrode within the first area; a second auxiliary layer arranged on the third electrode within the second area; and at least one fourth electrode arranged on the first auxiliary layer within the first area, the first auxiliary layer being interposed between the fourth electrode and the third electrode.
