Abstract

Each of particles for an antiglare film is provided with (a) a core particle composed of a first polymer, and (b) a shell layer, which covers at least a part of the surface of the core particle, has a thickness within a range of 0.1-2.0μm, and is composed of a second polymer. Each of the particles for the antiglare film has an average particle diameter of 0.8-10μm.
