Antireflection film having hard coating layer and display device including the same

An antireflection film comprising a hard coating layer and a low refractive index layer formed on the hard coating layer,

• wherein a roughness skewness (Rsk) of a concavo-convex shape of a surface of the low refractive index layer is greater than 0.5 and less than 5, and a slope angle of the concavo-convex shape of the surface of the low refractive index layer is greater than 0.01 degree and less than 0.2 degree, and
• wherein the low refractive index layer comprises a binder resin including a polysilsesquioxane in which at least one reactive functional group is substituted.
