We have developed a highly efficient backlight unit (BLU) with a polarization‐separating anisotropic layer on which asymmetric microstructures were embossed. Our BLU provides the polarized light along the direction normal to the anisotropic layer and has over 30% higher luminance than a BLU adopting a reflective polarizer.
