Optical film |
| abstract |
PROBLEM TO BE SOLVED: To provide an optical film having excellent visibility in a wide-angle direction. An optical film that includes a polyimide resin and a polyamide resin and has a total light transmittance of 85% or more and a haze of 0.5% or less. When the MD direction is defined and the direction perpendicular to the machine flow direction is defined as the TD direction, the slit width of the optical comb is 0.125 mm according to JIS K 7374 on at least one surface of the optical film. In the case obtained, the first reflection image clarity value C MD in the direction inclined by 60° in the MD direction from the direction perpendicular to the plane of the optical film and the direction inclined by 60° in the TD direction in the direction perpendicular to the vertical direction. The second reflection mappability value C TD is expressed by formula (1): 45% ≤ C MD ≤ 100% (1), formula (2): 30% ≤ C TD ≤ 100% (2). And the formula (3): 35%≦(C MD +C TD )/2≦100% (3).
