FUNCTIONAL FILM, POLARIZING PLATE AND IMAGE DISPLAY DEVICE

Provided are a functional film capable of achieving adhesion between a hard coat layer and a functional layer as well as achieving desired optical properties, and a polarizing plate and an image display device, both of which include the above functional film. One aspect of the present invention provides a functional film including a hard coat layer containing a binder resin and plural inorganic particles, and a functional layer closely attached to the front surface of the hard coat layer, wherein the hard coat layer includes a first region including a layer zone, in which denseness of the inorganic particles is 60% or more, from the front surface to a depth of 100 nm in the hard coat layer, and a second region, in which denseness of the inorganic particles is 59% or less, below a depth of 100 nm from the front surface in the hard coat layer.
