Abstract: The invention provides a broadband cholesteric liquid crystal film, a method for fabricating the same, a polarization device employing the same, and high light efficiency liquid crystal display employing the same. The cholesteric liquid crystal film is a single-layer liquid crystal material structure, and has a top surface and a bottom surface. Further, the cholesteric liquid crystal film includes a first region, a second region, and a third region, and the first region is adjacent to the top surface of the cholesteric liquid crystal film, the third region is adjacent to the bottom surface of the cholesteric liquid crystal film, and the second region is located between the first and third regions, and the average helical pitch P1 of the first region and the average helical pitch P3 of the third region are both larger than the average helical pitch P2 of the second region.
