1. A display device comprising a pixel comprising:
a primary inductor and a secondary inductor that are inductively coupled to each other, the secondary inductor comprising a first sub-inductor, and a second sub-inductor connected to the first sub-inductor;
a pixel circuit electrically connected to the primary inductor, and configured to control a current flowing through the primary inductor by using at least one transistor; and
a light emitting unit electrically connected to the secondary inductor, and comprising:
a first electrode electrically connected to the first sub-inductor;
a second electrode;
a third electrode electrically connected to the second sub-inductor;
a fourth electrode connected to the second electrode;
first light emitting elements connected in parallel between the first electrode and the second electrode; and
second light emitting elements connected in parallel to each other between the third electrode and the fourth electrode.
