REFLECTIVE POLARIZER, LIGHT SOURCE ASSEMBLY INCLUDING THE SAME AND LIQUID CRYSTAL DISPLAY INCLUDING THE LIQUID CRYSTAL FILM

摘要

PURPOSE: A reflective polarizer, and a light source assembly and liquid crystal display with the same are provided to have a fixed reflexibility for the entire wavelength range of visible light, thereby increasing brightness. CONSTITUTION: A reflective polarizer(10) comprises a liquid crystal layer(110) with a cholesteric liquid crystal and a filler(150) which is dispersedly arranged in the liquid crystal layer. A flat surface and a protruded surface are placed on the surface of the reflective polarizer. The protruded part is protruded from the flat surface. The liquid crystal layer includes liquid crystal pitch areas with different pitches of cholesteric liquid crystals.
