Light emitting element, display device using the same, and method of fabricating display device

A display device comprising:

• a pixel disposed in a display area, the pixel comprising:
• a first electrode;
• and
• a second electrode spaced apart from the first electrode;
• a light emitting element including a first end adjacent to the first electrode, and a second end adjacent to the second electrode, and comprising:
• a light emitting stack including:
• a first semiconductor layer;
• an active layer;
• a second semiconductor layer;
• and
• an electrode layer, the first semiconductor layer, the active layer, the second semiconductor layer, and the electrode layer being successively disposed in a direction from the second end to the first end of the light emitting element;
• an insulating pattern disposed on a part of the light emitting element and exposing the first and the second ends of the light emitting element;
• and
• a first contact electrode and a second contact electrode electrically connecting the first and the second ends of the light emitting element to the first electrode and the second electrode, respectively, wherein
• the light emitting element comprises an insulating film enclosing an outer circumferential surface of the light emitting stack and exposing a surface of the electrode layer and a surface of the first semiconductor layer respectively at the first and the second ends of the light emitting element, and
• the insulating film has an asymmetric structure such that an upper surface of the insulating film contacting the insulating pattern and a lower surface of the insulating film opposite to the upper surface in another direction have different lengths, the lengths being defined in the direction, the another direction and the direction perpendicular to each other.
