<P>PROBLEM TO BE SOLVED: To provide a polarizing film capable of forming a liquid crystal display device and an electro luminescence display device showing an excellent display characteristics without any display unevenness. <P>SOLUTION: A wettable polymer film is transported by a guide roll and thereby immersed in aqueous solvent in a swelling bath. In a swelling process, the polymer film is swollen, at least a first guide roll is arranged in the swelling path, and the polymer film is immersed in the aqueous solvent. When the polymer film is moved in the aqueous solvent, the polymer film is brought into contact with the first guide roll until the swelling becomes a saturated state, the polymer film is further dyed with a dichroism matter, and the polymer film is extended to thereby manufacture a polarizing film. <P>COPYRIGHT: (C)2004,JPO |
