방현성 및 투명성을 유지하면서, 또한, 번쩍거림을 억제할 수 있는 방현 필름을 제공한다. 본 발명의 방현 필름은, 투명 기재와, 그 투명 기재의 적어도 일방의 면에 배치된 방현층을 구비하고, 그 방현층의 그 투명 기재와는 반대측의 표면이 요철면이고, 그 요철면의 평균 간격 Sm 이 150 ㎛ ∼ 350 ㎛ 이고, 그 요철면의 평균 경사각 θa 가 0.1° ∼ 2.5° 이고, 그 요철면의 산술 평균 표면 조도 Ra 가 0.05 ㎛ ∼ 0.5 ㎛ 이다. This invention provides an anti-glare film that makes it possible to reduce sparkle without compromising anti-glare performance or transparency. Said anti-glare film comprises a transparent substrate and an anti-glare layer laid out on at least one surface of said transparent substrate. The surface of the/each anti-glare layer facing away from the transparent substrate is textured, with a mean clearance Sm between 150 and 350 µm, a mean angle of inclination θa between 0.1° and 2.5°, and an arithmetic mean roughness Ra between 0.05 and 0.5 µm.
