Abstract:
An antireflection film including a low reflective index layer and a hard coating layer, the low reflective index layer including: a binder resin including a crosslinked polymer of a photopolymerizable compound and polysilsesquioxane having at least one reactive functional group substituted thereon; and inorganic fine particles dispersed in the binder resin, wherein a ratio of internal haze (Hi) to total haze (Ha) is 97% or less and a variation in color coordinate value (b*) before and after alkaline treatment is 0.7 or less.
