Flexible oled panel for lighting device and method of manufacturing same

A method of manufacturing a flexible OLED panel for a lighting device, the method comprising:

• providing a substrate made of a polymer material and having a first light extracting pattern provided on a lower surface thereof;
• attaching the lower surface of the substrate to an auxiliary substrate on which an adhesive layer is disposed;
• disposing an auxiliary wiring pattern on the substrate;
• disposing a first electrode on the substrate on which the auxiliary wiring pattern is disposed;
• disposing a passivation layer on the first electrode, at least on an area on which the auxiliary wiring pattern is disposed;
• disposing an OLED light emitting structure on the first electrode on which the passivation layer is disposed;
• disposing a second electrode on the OLED light emitting structure;
• disposing an encapsulation layer on the second electrode;
• and
• detaching the auxiliary substrate.
