To provide an optical film having excellent visibility in a wide angle direction. An optical film including a polyimide-based resin and a polyamide-based resin and having a total light transmittance of 85% or more and a haze of 0.5% or less,in which,when a direction parallel to a machine direction in a plane of the optical film during production of the optical film is defined as an MD direction and a direction vertical to the machine direction is defined as a TD direction,for at least any one surface of the optical film, a first reflection image clarity value CMD in a direction inclined 60° in the MD direction from a vertical direction to the plane of the optical film and a second reflection image clarity value CTD in a direction inclined 60° in the TD direction from the vertical direction which are obtained when a slit width of an optical comb is 0.125 mm in accordance with JIS K 7374 satisfyFormula (1)45%≤CMD≤100% (1),Formula (2)30%≤CTD≤100% (2), andFormula (3)35%≤(CMD+CTD)/2≤100% (3). |
