Title:
光吸収異方性膜の製造方法
Document Type and Number:
Japanese Patent JP7223166
Kind Code:
B2
Abstract:
Provided is a method for producing a light absorption anisotropic film having a three-dimensional shape and having excellent alignment, which is capable of manufacturing a light absorption anisotropic film having a high degree of polarization even where a three-dimensional shape is provided by heating molding. The method includes a step of producing an intermediate laminate having an optical coating film formed using a liquid crystal composition containing a liquid crystalline compound and a dichroic substance, and an alignment film; a step of heating the intermediate laminate produced by the film forming step to impart a three-dimensional shape; an aligning step of aligning a liquid crystalline component included in the optical coating film in the intermediate laminate imparted with the three-dimensional shape by the heating molding step to produce a light absorption anisotropic film; and a step of curing the light absorption anisotropic film produced by the aligning step.
