1. A pixel comprising:
a first area and a second area partitioned in a first direction;
(1-1)-th and (2-1)-th electrodes disposed in the first area and spaced apart in a second direction different from the first direction;
(1-2)-th and (2-2)-th electrodes disposed in the second area and spaced apart in the second direction;
light emitting elements disposed between the (1-1)-th and (2-1)-th electrodes and between the (1-2)-th and (2-2)-th electrodes;
a contact electrode disposed on the (1-1)-th and (2-1)-th electrodes and the (1-2)-th and (2-2)-th electrodes;
an insulating layer disposed between each of the (1-1)-th and (2-1)-th electrodes and the (1-2)-th and (2-2)-th electrodes, and the contact electrode, and including a first opening exposing a portion of the (1-1)-th electrode; and
a first intermediate electrode electrically connecting the contact electrode on the (2-1)-th electrode and the contact electrode on the (1-2)-th electrode,
wherein the insulating layer completely covers the (2-1)-th electrode and the (1-2)-th electrode.
