Abstract: A pixel includes a light emitting area including a central portion and an outer portion, a non-light emitting area surrounding the light emitting area, a first electrode and a second electrode that are spaced apart from each other in the light emitting area, and a first light emitting element disposed between the first electrode and the second electrode. The first electrode and the second electrode are spaced apart from each other at a first interval in the central portion, and are spaced apart from each other at a second interval in the outer portion. The second interval is larger than the first interval. An interval between the first electrode and the second electrode gradually increases from the central portion to the outer portion.
