    摘要: 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.
