1. A display device comprising a pixel in a display area, the pixel comprising:
a first electrode and a second electrode spaced apart from each other;
a first insulating layer on one area of each of the first electrode and the second electrode and in an area between the first electrode and the second electrode, and having a first etch selectivity;
a first insulating pattern on the first insulating layer in the area between the first electrode and the second electrode, and having a second etch selectivity;
a light emitting element on the first insulating pattern, and having a first end and a second end;
a second insulating pattern having the second etch selectivity, and being on one area of the light emitting element such that the first end and the second end of the light emitting element are exposed; and
a third electrode and a fourth electrode configured to electrically connect the first end and the second end of the light emitting element to the first electrode and the second electrode, respectively.
