Abstract
An antireflection film, containing ultrafine particles, formed of a resin composition having excellent dispersibility of ultrafine particles in a binder resin and capable of preventing whitening, a polarizing plate, and a liquid crystal display device are provided. At least one resin layer is provided on a transparent substrate film directly or through other layer(s), and at least one of the resin layer has a controlled refractive index and is formed of a resin composition containing ultrafine particles. The outermost layer has a lower refractive index than an underlying layer in direct contact therewith. The resin composition contains a carboxyl-containing (meth)acrylate as part or the whole of a binder resin component. A polyfunctional acrylate having in its molecule three or more acryloyl groups may be added to the binder resin component in order to further enhance the properties of the hard coating.
