Abstract: An optical film has a base material and a hardcoat layer, in which a pencil hardness is 2H or higher, the number of times of folding endurance measured by an MIT tester is 1000 or more, an incident ray is made incident on the optical film from −60° with respect to a normal direction of the optical film, an angle width within which 10% of outgoing ray peak intensity is obtained is 6° or less, and an intensity of outgoing ray at 50° from the normal direction is 1% or less of the outgoing ray peak intensity. A method for manufacturing an optical film has a step of applying a hardcoat layer forming composition to a base material to provide a coating film, and a step of curing the coating film while bringing the coating film into contact with one smooth metal roll.
