The present invention relates to a quantum dot optical film and a quantum dot composition contained therein, wherein the quantum dot optical film comprises: a base film; a polymer matrix disposed on the base film; and a quantum dot-containing layer comprising a plurality of quantum dots dispersed in the polymer matrix, wherein the polymer matrix may include: a first photopolymerizable monomer having a carbon-carbon unsaturated bond at a terminal thereof; a second photopolymerizable monomer containing a thiol group at the terminal; and a cured product of the composition comprising at least one barrier material selected from a group consisting of halogen compounds and oxygen scavengers. The quantum dot optical film has excellent barrier properties even if a general optical film is used instead of a barrier film. 본 발명은 양자점 광학 필름 및 이에 포함되는 양자점 조성물에 관한 것으로서, 상기 양자점 광학 필름은 베이스 필름; 및 상기 베이스 필름 상에 배치되고, 고분자 매트릭스(polymer matrix); 및 상기 고분자 매트릭스 내에 분산된 복수의 양자점을 포함하는 양자점-함유층을 포함하고, 상기 고분자 매트릭스는 말단에 탄소-탄소 불포화 결합을 갖는 제1 광중합성 모노머; 말단에 티올기(thiol group)를 함유하는 제2 광중합성 모노머; 및 할로겐화합물 및 산소제거제로 이루어진 군에서 선택된 1종의 배리어 물질을 포함하는 조성물의 경화물을 포함한다.
