Abstract: A light emitting element, a display device including the same and a method of fabricating the same. The light emitting element may include an element rod including a first semiconductor layer, an active layer, and a second semiconductor layer. First and second contact electrodes may be respectively disposed on a first end surface and a second and opposite end surface of the element rod. A reflection layer may surround the first contact electrode and the element rod. An inner insulating layer may be disposed inside the reflection layer and surround the first contact electrode and the element rod. An outer insulating layer external to the reflection layer and may surround the first contact electrode and the element rod. A first inclination of side surfaces of the first semiconductor layer and the active layer and a second inclination of a side surface of the second semiconductor layer may be different.
