Abstract
In a transparent hard coat film, in which a transparent hard coat layer is formed on at least one surface of a transparent polymer film, the transparent hard coat layer is composed of at least an ionizing radiation curable organic-inorganic hybrid hard-coat agent and inorganic particles having a mean particle diameter of 1-10 μm. The organic-inorganic hybrid hard-coat agent preferably contains reactive silica. Such a transparent hard coat film of the present invention has well-balanced anti-glare effect and resolution and yet has hardness that is typically expressed as surface hardness.
