1. A display device comprising:
a substrate;
an anode electrode disposed on the substrate;
a first anti-contact layer disposed on the anode electrode and comprising molybdenum trioxide (MoO3);
a second anti-contact layer disposed on the first anti-contact layer and comprising molybdenum dioxide (MoO2); and
a pixel-defining layer disposed on the second anti-contact layer,
wherein the first anti-contact layer includes a first opening,
wherein the second anti-contact layer defines a second opening,
wherein the pixel-defining layer defines a third opening, and
wherein the first opening, the second opening and the third opening overlap one another in a thickness direction of the substrate and expose the anode electrode,
wherein the first opening that is of the first anti-contact layer surrounds the third opening that is of the pixel-defining layer when viewed from the top, and
wherein the second opening that is of the second anti-contact layer surrounds the first opening that is of the first anti-contact layer.
