| titleOfInvention | Optical film and flexible display device |
| abstract | [PROBLEMS] An optical film having excellent visibility in a wide-angle direction and visibility of a projected image and having a low in-plane retardation R 0 , and a flexible display device provided with the optical film are provided. [Solutions] An optical film comprising at least one resin selected from the group consisting of a polyimide-based resin and a polyamide-based resin, wherein the total light transmittance is 85% or more, the haze is 0.5% or less, and at 25°C has a tensile modulus of 5.1 GPa or more, and an in-plane retardation R 0 of 40 to 300 nm, When the direction parallel to the machine flow direction at the time of manufacture is called MD direction in the said optical film plane, and the direction perpendicular|vertical to the said machine flow direction is called TD direction, With respect to at least one surface of the optical film, according to JIS K 7374, obtained when the slit width of the optical comb is 0.125 mm, the direction perpendicular to the plane of the optical film in the direction inclined by 60 degrees in the MD direction A first reflection mapping value (C MD ) and a second reflection mapping value (C TD ) in a direction inclined by 60° from the vertical direction to the TD direction are, Equation (1): , Equation (2): , and Equation (3): An optical film that satisfies |
