The embodiments relate to a polyamide-based composite film with excellent curl characteristics, mechanical characteristics, and optical characteristics. The polyamide-based composite film comprises a base film comprising a polyamide-based polymer and a functional layer disposed on the base film, wherein when the polyamide-based composite film is placed on a surface light source such that the base film is in contact with the surface light source, light is irradiated from the surface light source, and the luminance value measured in the normal direction of the surface light source is 100%, the luminance value measured in the direction of 50° from the normal direction of the surface light source is 25% or more.

Polyamide-based composite film and display device comprising same

The embodiments relate to a polyamide-based composite film that not only has excellent curl characteristics, mechanical properties, and optical properties, but also exhibits a privacy protection effect at a wide angle of view and glossiness characteristics similar to those glass at a main angle of view, and to a display device comprising the same. There are provided a polyamide-based composite film that comprises a base film comprising a polyamide-based polymer; and a functional layer disposed on the base film, wherein a glossiness control value according to Equation 1 is 0 or more, and a displace device comprising the same.

Embodiments relate to a polyimide-based composite film, which comprises a base film comprising a polyimide-based resin; and a functional layer disposed on the base film, wherein when the side of the functional layer located opposite to the side in contact with the base film is referred to as a first side and when the side of the base film in contact with the functional layer is referred to as a second side, the leveling index represented by Equation 1 is less than 0.75.
