Abstract: An OLED panel for a lighting device is provided. The OLED panel for a lighting device may include a substrate divided into a light emitting area and a pad area formed outside of the light emitting area; an auxiliary wiring pattern disposed on the substrate, the auxiliary wiring pattern having a taper-shaped cross-section whose width is gradually narrower toward an upper portion thereof; a first electrode disposed on the substrate on which the auxiliary wiring pattern is disposed; a passivation layer disposed on the first electrode within an area where the auxiliary wiring pattern disposed; an OLED light emitting structure disposed on the first electrode on which the passivation layer is disposed; a second electrode disposed on the OLED light emitting structure; and an encapsulating layer disposed on the second electrode, and the passivation layer may have a cross-section corresponding to a cross-section of the auxiliary wiring pattern in the light emitting area. The OLED panel for a lighting device may have a wide light emitting area by reducing a passivation area on the auxiliary wiring pattern.

Abstract: An organic light-emitting diode panel for a lighting device includes a substrate including an array area having an emission area and a dummy area disposed outside the array area, an auxiliary wiring pattern, a first electrode, a passivation pattern, an OLED emission structure, a second electrode, an adhesive layer, and an encapsulation layer. The passivation pattern and the adhesive layer have an uneven boundary surface therebetween in the dummy area. Alternatively, a lower surface of the adhesive layer has a 3D structure. Thus, a moisture intrusion path between the passivation pattern and the adhesive layer of the dummy area of the substrate may be increased. Thus, degradation of the OLED emission structure due to external moisture intrusion may be reduced or prevented.
