Zusammenfassung:An optical film for reducing hot spots is disclosed. The optical film for reducing hot spots may include a first inverted prism sheet in which a plurality of first inverted prisms are disposed on the lower surface of a first base film, and a second inverted prism sheet in which a plurality of second inverted prisms facing a light source disposed at an edge of a light guide plate are disposed on the lower surface of a second base film. Here, the heights of the plurality of second inverted prisms can decrease at a predetermined ratio from one end relatively close to the light source among both ends of the second plurality of inverted prisms to a predetermined distance. 핫스팟을 저감하는 광학필름이 개시된다. 핫스팟을 저감하는 광학필름은 제1 복수의 역프리즘이 제1 베이스필름의 하면에 배치되는 제1 역프리즘시트 및 도광판의 에지(edge)에 배치된 광원에 대향하는 제2 복수의 역프리즘이 제2 베이스필름의 하면에 배치되는 제2 역프리즘시트를 포함할 수 있다. 여기서, 상기 제2 복수의 역프리즘의 높이는, 상기 제2 복수의 역프리즘의 양단 중 상기 광원으로부터 상대적으로 가까운 일단에서 기정의된 거리까지 기정의된 비율로 감소할 수 있다.
