Title
(EN) LAMINATED FILM
(FR) FILM STRATIFIÉ
(KO) 적층 필름
Abstract
(EN)
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.

La présente concerne un film stratifié comprenant une couche de retard présentant des caractéristiques de blocage contre un rayon ultraviolet spécifique même lorsqu'aucun absorbeur d'ultraviolets ni photostabilisant n'est mélangé en son sein. De plus, la présente invention concerne un film stratifié qui : présente une propriété de blocage des UV constante même en l'absence d'un absorbeur d'UV ou d'un photostabilisant, et est ainsi utilisé seul ou en association, selon les besoins, avec un bloqueur d'UV approprié ou un photostabilisant approprié; bloque sélectivement les rayons ultraviolets dans des zones nécessitant un blocage sans affecter les performances d'affichage telles que la couleur et la qualité d'image d'un dispositif d'affichage; ne nécessite pas une couche de blocage des ultraviolets séparée et peut ainsi adopter une forme mince; et présente une excellente durabilité.

본 출원은 자외선 흡수제나 광안정제가 배합되지 않은 상태에서도 특정한 자외선에 대해서 차단 특성을 나타내는 위상차층을 포함하는 적층 필름을 제공할 수 있다. 본 출원은 또한 자외선 흡수제나 광안정제가 없는 상태에서도 일정한 자외선 차단 특성을 나타내기 때문에 그 단독으로 또는 필요에 따라 적정한 자외선 차단제나 광안정제와 병용되어 디스플레이 장치의 색감 및 화질 등의 표시 성능에 영향을 주지 않으면서, 차단이 필요한 영역의 자외선을 선택적으로 차단할 수 있고, 별도의 자외선 차단층이 필요하지 않아서 얇게 형성될 수도 있으며, 내구성도 우수한 적층 필름을 제공할 수 있다.
