본 발명의 과제는, 반송성이 양호하고 헤이즈가 낮은 광학 필름을 제공하는 것이다. 본 발명의 광학 필름은, 시클로올레핀 수지와, 미립자와, 표면 조정제를 함유하는 광학 필름이며, 상기 표면 조정제가, 실리콘 재료, 불소계 재료, 비닐계 재료 및 아크릴계 재료 중 적어도 1종을 함유하고, 필름 양면 중 표면 조도 Ra가 높은 면의 표면 조도 Ra가, 3.0 내지 50.0㎚의 범위 내인 것을 특징으로 한다. PROBLEM TO BE SOLVED: To provide an optical film having good transportability and low haze. SOLUTION: The optical film of the present invention is an optical film containing a cyclic olefin resin, fine particles, and a surface conditioning agent. The optical film is characterized in that the surface conditioning agent contains at least one of a polysiloxane material, a fluorine-based material, a vinyl-based material and an acrylic-based material, and one of both sides of the film has a high surface roughness Ra ranging from 3.0 to 50.0 nm.
