Beschreibung
Zusammenfassung:	The present invention provides an optical film, a brightness enhancing film comprising the same and a backlight unit comprising the same. The optical film comprises: a first protection layer; a pattern layer installed on the first protection layer; and a second protection layer installed on the pattern layer. Therefore, the optical film can prevent performance of quantum dots from being lowered due to oxidation conditions. 본 명세서는 광학 필름, 이를 포함하는 휘도 향상 필름 및 백라이트 유닛을 제공한다.
