Abstract
With regard to an optical laminate having a applied film containing a lyotropic liquid crystalline compound, the present invention provides a method of producing an optical laminate that can prevent this applied film from becoming white turbidity. The present invention is a method of producing an optical laminate having a base material and a applied film laminated on at least one surface of the base material and containing a lyotropic liquid crystalline compound, where the method includes a step A of applying a solution containing at least one kind of a lyotropic liquid crystalline compound on a base material to form a wet applied film, and a step B of drying the wet applied film by spraying a wind onto the surface of the wet applied film simultaneously with this step A or after performing this step A and before the wet applied film is dried. In this step B, the wind is sprayed preferably in a tilted direction, and the wind direction is preferably from 0° to 60° or below relative to the plane of the base material.
