Title:
LAMINATED FILM
Document Type and Number:
WIPO Patent Application WO/2020/091549
Kind Code:
A1
Abstract:
The present application may provide a laminated film comprising a retardation layer exhibiting blocking characteristics against a specific ultraviolet ray even when no ultraviolet absorber or light stabilizer is mixed therein. In addition, the present application may provide a laminated film which: exhibits a constant UV blocking property even in the absence of a UV absorber or light stabilizer, and is thus used alone or in combination, as necessary, with an appropriate UV blocker or light stabilizer; selectively blocks ultraviolet rays in areas requiring blocking without affecting display performance such as color and image quality of a display device; does not need a separate ultraviolet blocking layer and thus may be thinly formed; and has excellent durability.
