Summary:Disclosed are an LED element, a manufacturing method thereof, and a display device including the LED element. The LED element comprises: a light emitting layer having a core-shell structure; a protective layer provided to cover a portion of an upper surface of a first semiconductor layer; a first electrode provided in an upper portion of the light emitting layer; and a second electrode provided in a lower portion of the light emitting layer. The light emitting layer includes the first semiconductor layer, an active layer, and a second semiconductor layer. The first electrode is provided to contact the first semiconductor layer. The second electrode is provided to contact the second semiconductor layer. LED 소자 및 그 제조방법과, LED 소자를 포함하는 디스플레이 장치가 개시된다. 개시된 LED 소자는, 코어-쉘 구조를 가지는 발광층과, 상기 제1 반도체층의 상면 일부를 덮도록 마련되는 보호층; 상기 발광층의 상부에 마련되는 제1 전극과, 상기 발광층의 하부에 마련되는 제2 전극을 포함한다. 상기 발광층은 제1 반도체층, 활성층 및 제2 반도체층을 포함한다. 상기 제1 전극은 상기 제1 반도체층과 접촉하도록 마련되며, 상기 제2 전극은 상기 제2 반도체층과 접촉하도록 마련된다.
