REFLECTTIVE POLARIZER, BACKLIGHT UNIT AND LIQUID CRYSTAL DISPLAY INCLUDING THE SAME

摘要

PURPOSE: A reflective polarizer, a backlight unit and a liquid crystal display including the same are provided to be thin and reduce a fabrication cost by reducing the number of optical components while having a wide band. CONSTITUTION: A diffuser(160) includes plural diffusing beads made of internal and external materials in order to transmit and diffuse a randomly polarized light. A reflective polarized film(170) reflects a second polarized light and transmit a first polarized light among the randomly polarized lights diffused through a diffuser. The diffuser includes a base film(161), diffusion beads(162) and an optical layer(164).
