Abstract:
An optical layered body wherein the additive amount of the antistatic agent can be reduced leading to a cost reduction while achieving high antistatic property simply and at a low cost. An optical layered body including an optical layered body comprising a light-transmitting substrate and at least a hard coat layer and a low refractive index layer, firmed on the light-transmitting substrate, wherein 1) the low refractive index layer is formed on the outermost surface, and 2) the low refractive index layer contains an antistatic agent.
