摘要 |
The present invention relates to a method and apparatus for manufacturing a reflective polarizer in which a polymer is dispersed. The reflective polarizer manufactured by the reflective polarizer manufacturing method according to the present invention may realize very superior optical properties of materials even though a significantly less number of birefringent polymers is provided on the same area in comparison to a conventional reflective polarizer including a birefringent polymer because the polymer within a base material has a plate shape. In addition, since the reflective polarizer includes a plate-shaped polymer having various optical thicknesses, the reflective polarizer may cover an entire visible ray region. Also, since a skin layer is formed in a molten state on at least one surface of a core layer, a separate adhesion process is not required. Thus, manufacturing costs may be significantly reduced, and also the optical properties of materials may be maximized. |
