PROBLEM TO BE SOLVED: To provide a manufacturing method of an optical film which reduces thickness unevenness of a coating liquid in coating by simultaneous multilayer coating.SOLUTION: A manufacturing method of an optical film, which is formed of at least two or more optical function layers containing polymers on a base material, includes: a process (1) of preparing a coating liquid for forming each optical function layer; and a process (2) of performing simultaneous multilayer coating of the coating liquid for forming the optical function layer on the base material. A TI value of the coating liquid for forming the optical function layer in the process (2) is 1.1 or less.SELECTED DRAWING: None |
