Abstract
An antistatic hard coat film for various displays is provided which can prevent electrostatic deposition of foreign materials and at the same time possesses excellent scratch resistance and hardness high enough not to cause a deterioration in transparency upon being rubbed. The antistatic hard coat film 5 comprises: a transparent substrate film 1; a transparent conductive layer 2, having a surface resistivity of preferably not more than 1012 &OHgr;/□, provided on the substrate film 1; and a hard coat 3 provided on the transparent conductive layer 2, the hard coat 3 preferably having such an anisotropic conductivity that the resistivity in the layer surface direction is higher than the resistivity in the layer thickness direction.
