Abstract: An embodiment provides a pixel including: a first bank pattern on a substrate; a first electrode and a second electrode on the first bank pattern and extending in a first direction; an insulating layer on the first electrode and the second electrode; a plurality of light emitting elements on the insulating layer between the first electrode and the second electrode; a first contact electrode electrically connecting the first electrode and the light emitting elements; and a second contact electrode electrically connecting the second electrode and the light emitting elements. The first electrode and the second electrode may be spaced from each other in a second direction different from the first direction on the first bank pattern.
