ABSTRACT:
The present invention provides a method of producing an optical laminate that can produce an optical laminate including an applied film containing a lyotropic liquid crystalline compound so that the thickness of the applied film will be approximately uniform. A method of producing an optical laminate having a base material and an applied film, comprising the step of applying a solution containing at least one kind of lyotropic liquid crystalline compound on the base material so as to form the applied film, wherein the concentration of the lyotropic liquid crystalline compound in the solution is lower than the isotropic phase—liquid crystal phase transition concentration. For example, the concentration of the lyotropic liquid crystalline compound in the solution is from (CIN−18)% by mass to (CIN−1)% by mass, where CINrepresents the isotropic phase-liquid crystal phase transition concentration.
