HARD COAT FILM, POLARIZING PLATE, AND IMAGE DISPLAY APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a hard coat film in which occurrence of an interference fringe is prevented and which is compatible with interlayer filling.SOLUTION: A hard coat film 1 includes: a transparent film 2; and a hard coat layer 3 formed on the transparent film 2. The surface free energy of the hard coat layer 3 is equal to or more than a certain value; the hard coat film 1 has a mixed region in which a component of the transparent film 2 and a component of the hard coat layer 3 are mixed; the refractive index of the mixed region continuously changes toward the thickness direction of the hard coat film; and a refractive index change gradient falls within a certain range.
