Abstract
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.
