摘要： There is provided a polarizing film with a high dichroic ratio obtained by causing lithium ions and cesium ions to coexist at a specific ratio in a coating fluid containing a lyotropic liquid crystalline dye having an acidic group. It is presumed that the reason why the dichroic ratio becomes higher is that lyotropic liquid crystalline dyes become easier to be uniformly oriented as a result of an appropriate extension of intermolecular distance among the lyotropic liquid crystalline dyes by coupling lithium ions having a small radius and cesium ions having a large radius to an acidic group of each of the lyotropic liquid crystalline dyes in the coating fluid.
