Abstract:
A polarizing plate comprising a polarizing element and an antireflection film, said antireflection film comprising:a transparent substrate film; andat least one resin layer provided on the transparent substrate film directly or through other layer(s), at least one of the resin layer(s) having a controlled refractive index and formed of a resin composition containing ultrafine particles, the outermost layer having a lower refractive index than the underlying layer in direct contact therewith and disposed on either the transparent substrate film or a side of the transparent substrate film,the resin composition containing a carboxyl-containing (meth)acrylate as part or the whole of a binder resin component, laminated onto the polarizing element,wherein the carboxyl-containing (meth) acrylate in the antireflection film has been prepared by reacting a compound having in its molecule one or more acid anhydrides with a hydroxyl-containing polyfunctional acrylate having in its molecule a hydroxyl group and three or more acryloyl groups.
