Oled panel for lighting device and method of manufacturing the same

A method of manufacturing an organic light emitting diode (OLED) panel for a lighting device, comprising:

• forming an auxiliary wiring pattern on a substrate, the auxiliary wiring pattern including a plurality of auxiliary wirings electrically coupled to each other, the substrate including a light emitting area and a pad area;
• forming a first electrode on the substrate on which the auxiliary wiring pattern is disposed;
• forming a polymer on the first electrode and between adjacent auxiliary wirings of the plurality of auxiliary wirings in the light emitting area;
• forming a passivation material on the first electrode and the polymer;
• removing the polymer and portions of the passivation material to form a passivation layer on respective upper portions of the plurality of auxiliary wirings in the light emitting area;
• forming an OLED light emitting structure on the first electrode on which the passivation layer is disposed;
• forming a second electrode on the OLED light emitting structure;
• and
• forming an encapsulating layer on the second electrode.

A device, comprising:

• a substrate;
• a wiring layer on the substrate, the wiring layer including a first wiring portion having an angled sidewall and an upper surface;
• a first electrode on the substrate and the wiring layer;
• a passivation layer on the first electrode, the passivation layer including a first passivation portion having an angled sidewall and an upper surface, the angled sidewall and the upper surface of the first passivation portion overlapping the angled sidewall and the upper surface, respectively, of the first wiring portion;
• an organic light emitting diode (OLED) light emitting structure on the first electrode and the passivation layer;
• and
• a second electrode on the OLED light emitting structure.
