New designs of lightguide systems, which emit linear polarized light with a high efficiency for transmissive and transflective LCD applications, are presented. These systems are equipped with nano‐ and/or micro‐structured films or coatings, which emit highly collimated or diffuse linearly polarized light with a high efficiency. The films are based on polarization‐selective scattering, reflection, or diffraction of light and their properties can be tuned to a large extent dependent on their envisioned application. For instance, edge‐lit lightguide systems are discussed, which combine a range of desirable features such as a high transparency in direct view, a direct emission of light at normal angles to the plane of the lightguide, and a purely unidirectional out‐coupling of light towards the LCD‐side. © 2005 The Japan Chemical Journal Forum and Wiley Periodicals, Inc.
