Abstract
Provided is a polyamideimide film and an image display device including the same and a polyamideimide film which may satisfy a high light transmittance while maintaining mechanical properties to significantly improve viewing properties, and may satisfy all of a low refractive index, a low retardation in the unit thickness direction (Rth), a low yellow index, a low haze, and the like to significantly improve optical properties such as transparency and visibility. An image display device including the same is also provided.
Claims17
A polyamideimide film comprising:
- a polyamideimide resin derived from an aromatic diamine, an acid anhydride, and an aromatic diacid dichloride;
- and inorganic nanoparticles;
- wherein a content of the inorganic nanoparticles is 20 to 65 wt % of the polyamideimide film, and
- a total light transmittance of the polyamideimide film is 90% or more as measured at 400 to 700 nm in accordance with the ASTM D1003 specification.
