Organic light emitting diode display

An organic light emitting diode display comprising:

• a substrate including a thin film transistor region in which a thin film transistor and an organic light emitting diode connected to the thin film transistor are disposed, and an auxiliary electrode region in which an auxiliary electrode is disposed;
• a passivation layer disposed on the auxiliary electrode and exposing at least a portion of the auxiliary electrode;
• a dummy pattern disposed on the passivation layer, the dummy pattern including a protrusion protruding more than the passivation layer in an area overlapping with the auxiliary electrode;
• a cathode included in the organic light emitting diode, divided by the protrusion, and exposing at least a portion of the auxiliary electrode, an end of the cathode being in direct contact with the auxiliary electrode;
• and
• a cover layer disposed on the cathode, and having continuity to cover the protrusion and the auxiliary electrode.
