Abstract

Bande adhésive, en particulier pour la fabrication ou le collage d'afficheurs optiques de données à cristaux liquides, qui possède deux couches d'adhésif (b, b') et au moins une feuille de support (a). Ladite bande adhésive est caractérisée en ce qu'elle possède des propriétés de réflexion de la lumière tant sur sa face supérieure que sur sa face inférieure et en ce qu'elle absorbe simultanément la lumière au moins dans la mesure où la lumière non réfléchie ne peut traverser ladite bande adhésive. Cette bande adhésive est en particulier conçue de sorte qu'elle possède une couche de vernis blanc (c) située au moins entre une face de la feuille de support et la couche d'adhésif se trouvant sur cette même face. De préférence, une couche métallique (d) est située entre la feuille de support et la couche de vernis blanc.
