Abstract: Provided are a functional film which is 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 10 including a hard coat layer 12 containing a binder resin 13 and plural inorganic particles 14, and a functional layer 16 closely attached to the front surface 12A of the hard coat layer 12, wherein the hard coat layer 12 includes a first region R1 that includes a layer zone, in which the denseness of the inorganic particles 14 is 60% or more, from the front surface 12A to a depth of 100 nm in the hard coat layer 12, and a second region R2, in which the denseness of the inorganic particles 14 is 59% or less, below a depth of 100 nm from the front surface 12A in the hard coat layer 12.
