Beschreibung
Zusammenfassung:	A backlight unit comprises: a substrate; a reflective film on the substrate; a plurality of semiconductor light emitting elements on the reflective film; a quantum dot composite film on a plurality of semiconductor light emitting elements; and an optical film on the quantum dot composite film. The quantum dot composite film comprises: a first barrier film; a quantum dot fluorescent film on the first barrier film; and a second barrier film on the quantum dot fluorescent film. The first barrier film can be a dichroic film. Therefore, an objective of the present invention is to provide the quantum dot composite film bonded to a variety of light functional films. 백라이트 유닛은 기판과, 기판 상에 반사 필름과, 반사 필름 상에 복수의 반도체 발광소자와, 복수의 반도체 발광소자 상에 양자점 복합 필름과, 양자점 복합 필름 상에 광학 필름을 포함한다. 양자점 복합 필름은 제1 배리어 필름, 제1 배리어 필름 상에 양자점 형광체 필름 및 양자점 형광체 필름 상에 제2 배리어 필름을 포함한다. 제1 배리어 필름은 다이크로익 필름일 수 있다.
