1. An anti-reflective film comprising:
a hard coating layer; and a low refractive index layer,
wherein a particle-mixed layer containing both hollow inorganic nanoparticles and solid inorganic nanoparticles and having a thickness of 1.5 nm to 22 nm exists in the low refractive index layer, and
wherein the anti-reflective film has a ratio of the reflectance at a wavelength of 400 nm to the reflectance at a wavelength of 550 nm of 1.3 to 2.7.
