1. A pixel comprising:
a light emitting area, a non-light emitting area adjacent to the light emitting area, and a separating area spaced apart from the light emitting area, the non-light emitting area being disposed between the light emitting area and the separating area;
a first pattern and a second pattern that are spaced apart from each other along a first direction in the light emitting area and respectively extend along a second direction;
a first light emitting element disposed between the first pattern and the second pattern;
a first electrode electrically connected to a first end portion of the first light emitting element;
a second electrode electrically connected to a second end portion of the first light emitting element, the second electrode being connected to a different electrical node than the first electrode; and
a bank disposed in the non-light emitting area, wherein
the first electrode and the second electrode extend from the light emitting area through the non-light emitting area to the separating area,
the second pattern extends from the light emitting area through the non-light emitting area to the separating area, overlaps an edge of the bank, and is disposed in an area between the first electrode and the second electrode at a boundary of the non-light emitting area and the separating area.
 
24. A display device comprising:
a pixel disposed in a display area, wherein
the pixel includes:
a light emitting area, a non-light emitting area adjacent to the light emitting area, and a separating area spaced apart from the light emitting area, the non-light emitting area being disposed between the light emitting area and the separating area; and
a first pattern and a second pattern that are spaced apart from each other along a first direction in the light emitting area and respectively extend along a second direction;
a light emitting element disposed between the first pattern and the second pattern;
a first electrode electrically connected to a first end portion of the light emitting element;
a second electrode electrically connected to a second end portion of the light emitting element, the second electrode being connected to a different electrical node than the first electrode; and
a bank disposed in the non-light emitting area,
the first electrode and the second electrode extend from the light emitting area through the non-light emitting area to the separating area, and
the second pattern extends from the light emitting area through the non-light emitting area to the separating area, overlaps an edge of the bank, and is disposed in an area between the first electrode and the second electrode at a boundary of the non-light emitting area and the separating area.
