Abstract
A reflective polarizer of the invention has excellent optical properties even though a very small number of polymer components per unit area is disposed inside a matrix thereof compared to reflective polarizers of the related art, which include birefringent polymer, since the polymer inside the matrix has a plate-like shape. This is advantageous for covering the entire range of visible light, since a plate-like polymer having a variety of optical thicknesses can be used. The additional processing of bonding the skin layer is not performed, since the skin layer is formed on at least one surface of the core layer in the state in which it is molten. This can greatly reduce manufacturing costs, and is advantageous in that it maximizes optical properties in a limited thickness.
