METHOD FOR PRODUCTION OF OPTICAL LAMINATE, AND IMAGE DISPLAY DEVICE

摘要

Disclosed is a method for producing an optical laminate having a coating film comprising a lyotropic liquid crystal compound, which can make the coating film approximately uniform in thickness. Specifically disclosed is a method for producing an optical laminate comprising a base material and a coating film. The method comprises the step of applying a solution containing at least one lyotropic liquid crystal compound on the base material to form a coating film, wherein the concentration of the lyotropic liquid crystal compound in the solution is lower than the (isotropic phase)-(liquid crystal phase) transition concentration. Preferably,the concentration of the lyotropic liquid crystal compound in the solution is (C_IN-18) mass% to (C_IN-1) mass%, wherein C_IN represents the (isotropic phase)-(liquid crystal phase) transition concentration.
