Optical film |
| abstract |
[Problem] An optical film having excellent bending resistance and excellent stability of optical properties under high temperature and high humidity is provided. [Solutions] The optical film of the present invention comprises a polyamideimide resin, and is represented by formula (1) ΔHz<0.5 (1) [In formula (1), ΔHz denotes Hz a -Hz b , and Hz a is a mandrel test that returns to a flat shape by bending once with a bending radius of 1 mm at room temperature (JIS K 5600-5-1:1999). Conformity) represents the haze (%) of the optical film after, Hz b represents the haze (%) of the optical film before the mandrel test] Meets the relationship. |
