PURPOSE: A reflective polarizer including a bead coating layer is provided to improve scratch resistance while enhancing an optical property including brightness. CONSTITUTION: Skin layers (186, 187) are formed at both sides of a core layer (180). Bead coating layers (188,189) are formed at one side of the skin layer. A core layer (180) is separated into two groups (A, B). The average optical thicknesses of polymers (181, 182) which are a first element included in the group A and the average optical thicknesses of polymers (183, 184) which are a first element included in the group B are different. The wavelength area of different lights is reflected. |
