POLARIZING FILM, CIRCULAR POLARIZING PLATE AND METHOD OF PRODUCING THE SAME

摘要

PURPOSE: A polarizing film, a circular polarizing plate, and a manufacturing method thereof are provided to effectively execute a thin film process and to offer an excellent neutral color property. CONSTITUTION: A polarizing film comprises a polymer, one-kind dichroic dye, and two-kind dichroic dye. The polymer is comprised of a polymeric liquid-crystalline compound. The one-kind dichroic dye forms the absorption range of 380-550nm when the optical absorption is measured by dispersing the one-kind dichroic dye among the polymers. The two-kind dichroic dye forms the absorption range of 550-700nm. The two-kind dichroic dye includes a dichroic dye which forms the absorption range of 600-700nm.
