Abstract

[Problème] Fournir une feuille protectrice transparente ayant une surface adhésive à laquelle n'adhèrent pas les traces de doigts et analogues. L'invention vise par ailleurs à fournir une feuille protectrice qui reste en place lorsqu'elle est collée par adhérence à une zone transparente ou à un écran à cristaux liquides. [Solution] Une feuille protectrice (10) possède une feuille pelable (20), un corps de feuille protectrice (30) et des parties de maintien (40, 40). Plus précisément, la feuille pelable (20) et le corps de feuille protectrice (30) forment une structure bicouche, et la structure bicouche comporte les parties de maintien (40, 40). Si l'on colle par adhérence la feuille protectrice à un écran à cristaux liquides par maintien des parties de maintien (80, 80), il n'y a aucun risque que des traces de doigts et analogues n'adhèrent au corps de feuille protectrice (30).
