It is possible to obtain a polarizing film having a high dichroic ratio by using a liquid-crystalline coating solution in which a small quantity of a second lyotropic liquid-crystalline low-molecular compound is mixed with a first lyotropic liquid-crystalline low-molecular compound. The second lyotropic liquid-crystalline low-molecular compound has a mole number smaller than the first lyotropic liquid-crystalline low-molecular compound. The molecular size of the second lyotropic liquid-crystalline low-molecular compound is smaller than that of the first lyotropic liquid-crystalline low-molecular compound.

摘要:
A method for manufacturing a polarizing plate in which a transparent protective film is provided on at least one surface of a polarizer with an adhesive layer interposed therebetween, wherein an adhesive is coated on a surface of the transparent protective film on which the adhesive layer is formed or/and a surface of the polarizer on which the adhesive layer is formed to form the adhesive layers, and thereafter, an aqueous liquid is caused to be present on an adhering surface when the transparent protective film and the polarizer are continuously adhered to each other with the adhesive layer interposed therebetween. A polarizing plate having uniform polarization characteristics, and excellent in durability is obtained by the method.
