1. A display device comprising:
a circuit element layer disposed on a substrate;
a first insulation layer disposed on the circuit element layer;
a first conductor pattern disposed on the first insulation layer and including one or more metal layers;
a second insulation layer disposed on the first conductor pattern;
a second conductor pattern disposed on the second insulation layer;
a third insulation layer disposed on the second conductor pattern;
an electrode of a light emitting diode disposed on the third insulation layer; and
a pixel defining layer disposed on the third insulation layer and including an opening that overlaps the electrode of the light emitting diode, wherein
the opening overlaps the first conductor pattern,
in a plan view, an area of the opening matches an area of the first conductor pattern or is disposed inside the area of the first conductor pattern, and
the first conductor pattern is electrically connected with a drain electrode of a first transistor and a drain electrode of a second transistor to each other, a gate electrode of the first transistor receiving an inverted scan signal, and a gate electrode of the second transistor receiving an initialization control signal.
