하드 코트 필름 (1) 은, 필름 기재 (10) 의 일주면 상에 하드 코트층 (11) 을 구비한다. 하드 코트층은, 바인더 수지 및 무기 필러를 포함하고, 바인더 수지 100 중량부에 대한 상기 무기 필러의 함유량이 20 ∼ 80 중량부이다. 필러의 평균 1 차 입자경은 25 ∼ 70 ㎚ 가 바람직하다. 하드 코트층의 표면의 산술 평균 조도는 2 ㎚ 이상이 바람직하다. 하드 코트층의 확산 반사광의 b는 -0.2 이상이 바람직하다. A hard coat film (1) is provided with a hard coat layer (11) on one principal surface of a film substrate (10). The hard coat layer includes a binder resin and an inorganic filler, the content of the inorganic filler with respect to 100 parts by weight of the binder resin 100 being 20-80 parts by weight. The average primary particle diameter of the filler is preferably 25-70 nm. The arithmetic mean roughness of the surface of the hard coat layer is preferably at least 2 nm. The b* of diffuse reflected light from the hard coat layer is preferably -0.2 or greater.
