    Abstract: Provided are: an optical film, wherein interference fringes can be suppressed from being generated, cloudiness is not observed, and a manufacture cost can be reduced. In accordance with one aspect of the present invention, there is provided an optical film 10 including a functional layer 12, wherein the functional layer 12 has a concavo-convex surface 12A; and in a state in which the concavo-convex surface 12A is irradiated with parallel light travelling in a direction sloped at 10° with respect to a normal direction N of the optical film 10, in an angle distribution of reflected light intensities measured in a plane including both directions of the normal direction N and the travelling direction T of the parallel light, a value obtained by subtracting ½ angle width from 1/100 angle width is 0.7° or more and 1.4° or less.

    Abstract: Provided is an optical layered body which sufficiently suppresses generation of interference fringes and curls, can make a hard coat layer thin, and prevent an increase in production cost. Provided is an optical layered body having a hard coat layer formed on one surface of a light-transmitting substrate, wherein the hard coat layer has a surface roughness on its surface and the surface roughness satisfies the following inequalities of θa and Kr where θa is an average inclination angle of the uneven part and Kr is Kurtosis of the unevenness: 0.01°≦θa≧0.10° 1≦Kr≦3.
