Abstract A backlight for liquid crystal display illumination is presented, consisting of a commercial birefringent liquid crystalline polymeric layer innovatively laminated onto a micro‐structured plastic light guide. S‐polarized light is preferentially extracted from the light guide, and the efficiency was measured to be 1.78 time higher than in for a conventional unpolarized light emitting backlight.
