Abstract
The embodiments relate to a polyamide-based composite film that has excellent curl characteristics, mechanical properties, and optical properties, as well as, in particular, is effective in preventing reflection in the visible light region, remarkably reduces the rainbow phenomenon, and achieves a texture similar to that of glass, and a display device comprising the same. There are provided a polyamide-based composite film, which comprises a base film comprising a polyamide-based polymer; and a functional layer disposed on the base film, wherein the in-plane retardation (Re) measured with light having a wavelength of 550 nm is 100 nm to 220 nm, and a display device comprising the same.
