MULTILAYER REFLECTIVE POLIZER HAVING BEAD COATING LAYER

摘要

PURPOSE: A multi layer reflective polarizer including a bead coating layer is provided to improve scratch resistance while enhancing an optical property including brightness. CONSTITUTION: Skin layers (189,190) are integrally formed at both sides of a core layer (180). Bead coating layers (191,192) are formed at one side of the skin layer. The core layer is separated into two groups. The group A alternatively laminates first layers (181, 183) which are first element and second layers (182, 184) which are second element. The first layer and the second layer are defined as one repetition unit (R1) and the group A can include at least 25 repetition units. The group B alternatively laminates first layers (185,187) and second layers (182,184). The first layer and the second layer are defined as one repetition unit (R2) and the group B can include at least 25 repetition units.
