REFLECTIVE POLARIZER DISPERED POLYMER

摘要

PURPOSE: A reflective polarizer is provided to have excellent optical matter property even if a few double reflection polymers are arranged inside base material. CONSTITUTION: Skin layers(181, 182) are formed on both sides of a core layer(180). A plurality of polymers(183, 184, 185, 186) is dispersed inside the core layer. The aspect ratio of the plurality of dispersed polymers is less than 1/1000. The aspect ratio is a ratio of a short axis length about a long axis length based on a vertical cross section of a longitudinal direction of the polymers. The plurality of polymers has proper optical thickness in order to reflect a wavelength area of desired light and has thickness deviation of a proper range.
