Zusammenfassung:	One embodiment of an optical film includes a first pattern layer including a base unit and a plurality of protrusion units disposed on the base unit, and having a first refractive index, and a second pattern layer disposed on the first pattern layer and having a second refractive index greater than the first refractive index. Each of the plurality of protrusion units includes a bottom surface adjacent to the base unit, a ceiling surface parallel to the bottom surface, and a side surface disposed between the bottom surface and the ceiling surface. The side surface includes three or more sub-slanted surfaces having different inclination angles, or at least one curved surface convex in the direction of the second pattern layer, so as to improve the display quality on the side surface of the display device. 일 실시예의 광학 필름은 베이스부 및 베이스부 상에 배치된 복수 개의 돌출부들을 포함하며, 제1 굴절률을 갖는 제1 패턴층 및 제1 패턴층 상에 배치되고, 제1 굴절률 보다 큰 제2 굴절률을 갖는 제2 패턴층을 포함하고, 복수 개의 돌출부들 각각은 베이스부와 인접한 바닥면, 바닥면과 평행한 천장면 및 바닥면과 천장면 사이에 배치된 측면을 포함한다. 측면은 경사각이 서로 다른 3개 이상의 서브 경사면들을 포함하거나, 또는 제2 패턴층 방향으로 볼록한 적어도 하나의 곡면을 포함하여, 표시 장치의 측면에서의 표시 품질을 개선할 수 있다.
