A transparent hard coat film having excellent hardness and transmitted resolution, in which an interference fringe attributable to non-uniform thickness of the transparent hard coat layer is not noticeable, is provided. The transparent hard coat film of the invention has a transparent hard coat layer formed on at least one surface of a transparent polymer film, wherein the transparent hard coat film has a b* value in the L*a*b* color space system of 0.5 or less.

Transparent hard coat film, transparent conductive hard coat film, touch panel using this film, and liquid crystal display device using this touch panel

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 &#x3bc;m. 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.
