Abstract: The present application relates to an OLED panel for a lighting device and a method of manufacturing the same. An OLED panel for a lighting device includes: a substrate; a auxiliary wiring pattern having a plurality of wiring lines disposed on the substrate; a first electrode disposed on the substrate where the auxiliary wiring pattern is disposed, and having a planarized upper surface; a passivation layer disposed on the first electrode and disposed at least in an area above the auxiliary wiring pattern; an OLED emission structure disposed on the first electrode; and a second electrode disposed on the OLED emission structure. In the OLED panel for a lighting device, luminance uniformity may be improved through a dual auxiliary wiring pattern, and the upper surface of the first electrode is planarized. Accordingly, the area of the passivation layer is reduced, and thus a light-emitting area may be increased.

Abstract: An organic light-emitting display device and a method of manufacturing the same are disclosed. The organic light-emitting display device includes a touch sensor having a plurality of touch electrodes on an encapsulation stack covering a light-emitting element. The touch electrodes are formed at a low temperature and are crystallized through an annealing process, whereby it is possible to prevent damage to an organic light-emitting layer at the time of forming the touch electrodes. Thus the touch electrodes can be formed on the encapsulation stack without an additional bonding process to bond the touch sensor to the organic light-emitting display device.
