Abstract

La présente invention concerne une structure de fixation de groupes de films optiques à la lumière frontale et à la lumière d'arrière plan, qui comprend principalement un tube à cristaux liquides et un organe d'éclairage destiner à éclairer ce tube à cristaux liquides. Cette structure se caractérise en ce qu'au moins un film entre un substrat et une source lumineuse peut être fixé par un moyen de fixation non visqueux. La fiabilité et la capacité de recyclage de ces films ne seront pas testés du fait du chauffage et de la température élevée pendant la procédure de test qui suit.
