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.
