Abstract:
It is an object of the present invention to provide an improved optical layered body with reduced scintillation, gloss blackness, color effects and interference fringes, while maintaining antistatic and antiglare performance.The optical layered body comprises, in order, an antistatic layer, an antiglare layer and a low refractive index layer on a light-transmitting substrate, The antistatic layer is a thin resin layer containing antimony-doped tin oxide and a diffusion filler, and having a predetermined surface roughness on its surface.
