Abstract
(EN)
This polarizing film with an adhesive layer comprises a polarizing film and an adhesive layer. The polarizing film comprises a polarizing element, a transparent protective film on only one surface of the polarizing element, and a conductive layer on the other one surface of the polarizing element with a transparent layer therebetween that is no more than 10 μm thick and that is formed directly on the polarizing element. The adhesive layer is provided on the polarizing film with the aforementioned conductive layer interposed therebetween. Even in the case that a conductive layer is provided on the side of the polarizing element of the one-side-protected polarizing film, which has the transparent protective film on only one surface of the polarizing element, decoloration of the end part of the polarizing element in a humidified environment can be suppressed.

L'invention concerne un film polarisant comprenant une couche adhésive, lequel consiste en un film polarisant et une couche adhésive. Le film polarisant comprend un élément polarisant, un film protecteur transparent sur une seule surface de l'élément polarisant, et une couche conductrice sur l'autre surface de l'élément de polarisation avec une couche transparente intercalée entre elles n'étant pas supérieure à 10 µm d'épaisseur et formée directement sur l'élément de polarisation. La couche adhésive est disposée sur le film polarisant, la couche conductrice susmentionnée étant intercalée entre ces derniers. Même dans le cas où une couche conductrice est disposée sur le côté de l'élément polarisant du film polarisant protégé sur un côté, possédant le film protecteur transparent sur une seule surface de l'élément polarisant, la décoloration de l'extrémité de l'élément polarisant dans un environnement humidifié peut être supprimée.
