  • Patent number: 10421239
    Abstract: It is an object of the invention to provide an optical laminate-producing method in which a polarizing film having the desired optical properties can be conveniently formed on a resin film as a substrate without performing any surface alignment treatment such as rubbing on the resin film. The invention relates to a method for producing an optical laminate comprising a stretched resin film and a polarizing film, the method comprising the steps of: preparing a stretched resin film; applying a solution of a liquid crystal compound in an isotropic phase state to the stretched resin film; and forming a polarizing film in which the liquid crystal compound is aligned by solidifying the applied liquid crystal compound solution, wherein a slow axis of the stretched resin film is substantially parallel to an absorption axis of the polarizing film, and the stretched resin film undergoes no surface alignment treatment.
