More Information
Summary:Provided are an electroluminescent element, a manufacturing method thereof, and a display device including the same, wherein the electroluminescent element comprises: a first electrode; a hole transport layer located on the first electrode; a light emitting layer located on the hole transport layer and including a luminous body particle; an electron transport layer located on the light emitting layer and including a metal oxide particle-organic polymer composite; and a second electrode located on the electron transport layer. An organic polymer is contained in a range of 7 wt% to 30 wt% based on a total weight of the electron transport layer. Therefore, the present invention has an improved luminous efficiency and lifespan characteristics. 제1 전극과, 제1 전극 위에 위치한 정공 수송층과, 정공 수송층의 위에 위치하며, 발광체 입자를 포함하는 발광층과, 발광층 위에 위치하며, 금속 산화물 입자-유기 고분자 복합체를 포함하는 전자 수송층, 및 전자 수송층 위에 위치하는 제2 전극을 포함하며, 유기 고분자는 전자 수송층의 총 중량을 기준으로 7 중량% 내지 30 중량% 함유되어 있는 전계 발광 소자와, 그 제조 방법, 및 이를 포함하는 표시 장치가 제공된다.
