    摘要: The present invention relates to an optical film structure having improved properties and comprising at least one prism film and/or diffuser film as well as a multilayer optical film, wherein the multilayer optical film has at least one top film having an outer layer directed towards the prism film and/or diffuser film and made from a plastics composition containing a transparent thermoplastic and at least one quaternary ammonium salt of a perfluoroalkylsulfonic acid as lubricant additive. According to the invention the outer layer has at least one coefficient of sliding friction of 5 μm (R3z in accordance with ISO 4288). The invention also provides a backlight unit containing the improved film structure and the use of the optical film structure according to the invention for liquid crystal screens.
