たハードコートフィルムを提供することにある。Accordingly, the present inventors have conducted intensive studies on the visibility of a hard coat film using fine particles, and as a result, when a display was viewed through the hard coat film, the light of a backlight or the like was observed. However, large scattering in the large particles in the film or an increase in the percentage of light backscattered causes glare, which deteriorates visibility, so that, as in the conventional case, the particle size distribution is completely considered. In a normal filler compounding method which is not included, visibility is deteriorated by particles having a large particle size which is inevitably contained, and in particular, transmission clarity is set to 20% or more, and reflection clarity is set to 20.1% or less. found that it is possible to improve visibility by be Rukoto, we have reached the present invention. Accordingly, an object of the present invention is to provide a hard coat film which is excellent not only in antiglare properties but also in visibility.
