Summary:Provided is a manufacturing method of a light emitting element which comprises the following steps of: forming a first electrode; forming a light emitting layer including quantum dots on the first electrode; forming an electron auxiliary layer on the light emitting layer; and forming a second electrode on the electron auxiliary layer. The step of forming the electron auxiliary layer comprises the following steps of: forming an electron auxiliary layer including a plurality of metal oxide nanoparticles; and contacting the plurality of metal oxide nanoparticles with a base containing a hydroxyl group (OH). 제1 전극을 형성하는 단계, 상기 제1 전극 위에 양자점을 포함하는 발광층을 형성하는 단계, 상기 발광층 위에 전자 보조층을 형성하는 단계, 그리고 상기 전자 보조층 위에 제2 전극을 형성하는 단계를 포함하고, 상기 전자 보조층을 형성하는 단계는, 복수개의 금속 산화물 나노 입자들을 포함하는 전자 보조층을 형성하는 단계, 및 상기 복수개의 금속 산화물 나노 입자들과 하이드록시기(OH)를 포함하는 염기(base)를 접촉시키는 단계를 포함하는, 발광 소자의 제조 방법을 제공한다.
