Display device including auxiliary electrode

A display device comprising:

• a base substrate;
• a circuit layer disposed on the base substrate;
• a first electrode disposed on the circuit layer;
• an auxiliary electrode disposed on the circuit layer and spaced apart from the first electrode;
• a pixel defining layer disposed on the circuit layer and the first electrode, and having an opening which exposes a portion of the first electrode;
• a light-emitting layer disposed in the opening;
• and
• a second electrode disposed on the light-emitting layer,
• wherein the auxiliary electrode includes:
• a first layer including the same material as a material of the first electrode;
• a second layer disposed on the first layer and including silver (Ag) or silver alloy (Ag alloy);
• and
• a third layer disposed on the second layer and including molybdenum (Mo) or molybdenum alloy (Mo alloy), and
• wherein the second electrode is in contact with a side surface of the second layer of the auxiliary electrode, and
• an upper surface of the auxiliary electrode including the first to the third layers is disposed higher than an upper surface of the first electrode from the base substrate.
